According to the given information, the slope of the line is -1.

In mathematics, slope is a measure of how steep a line is, or how much y (vertical) changes for a given x (horizontal) change. It is represented by the letter "m" and is calculated as the change in y divided by the change in x, or rise over run. The slope can be positive, negative, zero, or undefined.

The answer is D, -1; the amount of water decreases by 1 gallon per minute.

To find the slope of the line, we need to use the slope formula:

slope = (change in y)/(change in x)

In this case, the change in y represents the change in the amount of water, and the change in x represents the change in time.

Option A says that the slope is 2/3, which means that for every 3 minutes, the amount of water decreases by 2 gallons. This is incorrect because as time increases, the amount of water should decrease, so the slope should be negative.

Option B says that the slope is -2/3, which means that for every 3 minutes, the amount of water decreases by 2 gallons. This is the same as option A but with a negative slope, which is correct because the amount of water decreases over time.

Option C says that the slope is -3/2, which means that for every 2 minutes, the amount of water decreases by 3 gallons. This is incorrect because the amount of water should decrease by the same amount every minute.

Option D says that the slope is -1, which means that for every minute, the amount of water decreases by 1 gallon. This is the correct answer because it describes a constant rate of change in the amount of water over time.

Therefore, according to the given information, the slope of the line is -1.

Answer:

x < 2

Step-by-step explanation:

Let's actually solve the given inequality 3x + 1 < 7.  First we want to combine the constants into one:  3x < 6.  Solving for x, we get x < 2.

The graph you have chosen as your answer is correct.  x does not equal 2, but rather is less than 2, as the given inequality states.  Since x is less than 2, we start at the (open) circle at 2 and move to the left.

Answer:

A1 = Triangle (this can be calculated using the formula 1/2×base×height. Base =9 and height =13)

A2 = Square (3×5=15)

Answer:

615.8in^3

Step-by-step explanation:

Given data

Radius= 14in

The expression for the area of circle is given as

A= πr^2

Area= 3.142*14^2

Area= 3.142*196

Area= 615.832in^3

Hence the area is 615.8in^3

Answer:

A) r=d/t

B) 221,760 feet per hour

C) 42 miles per hour

D) in this scenario feet per mile makes more sense since the distance is listed in feet.

Step-by-step explanation:

A) you solve for r by divided both sides of the equation by (t)time

B) you take your formula r=d/t and substitute the values of (d) and (t) with 665,280 feet and 3 hours.

C) convert feet to miles by dividing the given amount of feet by 5280 since there are 5,280 feet in 1 mile

D) use feet to make the calculations easier and to avoid making a mistake in converting feet to miles

Answer:

y= -1x+7

or

y = -1x + b

Step-by-step explanation:

You want to find the equation for a line that passes through the two points:

(2,5) and (4,3).

First of all, remember what the equation of a line is:

y = mx+b

Where:

m is the slope, and

b is the y-intercept

First, let's find what m is, the slope of the line...

The slope of a line is a measure of how fast the line "goes up" or "goes down". A large slope means the line goes up or down really fast (a very steep line). Small slopes means the line isn't very steep. A slope of zero means the line has no steepness at all; it is perfectly horizontal.

For lines like these, the slope is always defined as "the change in y over the change in x" or, in equation form:

So what we need now are the two points you gave that the line passes through. Let's call the first point you gave, (2,5), point #1, so the x and y numbers given will be called x1 and y1. Or, x1=2 and y1=5.

Also, let's call the second point you gave, (4,3), point #2, so the x and y numbers here will be called x2 and y2. Or, x2=4 and y2=3.

Now, just plug the numbers into the formula for m above, like this:

m=

3 - 5

4 - 2

or...

m=

-2

2

or...

m=-1

So, we have the first piece to finding the equation of this line, and we can fill it into y=mx+b like this:

y=-1x+b

Now, what about b, the y-intercept?

To find b, think about what your (x,y) points mean:

(2,5). When x of the line is 2, y of the line must be 5.

(4,3). When x of the line is 4, y of the line must be 3.

Because you said the line passes through each one of these two points, right?

Now, look at our line's equation so far: y=-1x+b. b is what we want, the -1 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specfically passes through the two points (2,5) and (4,3).

So, why not plug in for x and y from one of our (x,y) points that we know the line passes through? This will allow us to solve for b for the particular line that passes through the two points you gave!.

You can use either (x,y) point you want..the answer will be the same:

(2,5). y=mx+b or 5=-1 × 2+b, or solving for b: b=5-(-1)(2). b=7.

(4,3). y=mx+b or 3=-1 × 4+b, or solving for b: b=3-(-1)(4). b=7.

See! In both cases we got the same value for b. And this completes our problem.

The equation of the line that passes through the points

(2,5) and (4,3)

is

y=-1x+7
