Answer:

y - 4 = -2(x - 5)

Step-by-step explanation:

point slope form is  y-y1 = m(x-x1)

the original equation is given in slope intercept form y = mx + b

Parallel lines have equal slopes so from the given equation  y = -2x-3

the slope m = -2.

Use the given point (5,4) as (x1, y1).

y - 4 = -2(x - 5)

Answer:

[tex]\displaystyle y - 4 = -2(x - 5)[/tex]

Step-by-step explanation:

Parallel equations have SIMILAR RATE OF CHANGES [SLOPES], so −2 remains as is as you proceed with plugging the information into the Point-Slope Formula:

[tex]\displaystyle [5, 4] \\ \\ \boxed{y - 4 = -2(x - 5)}[/tex]

Answer:

  y -1 = 1/2(x +2)

Step-by-step explanation:

The line has a rise of 1 grid unit for each 2 that it goes to the right. Its slope is then m = rise/run = 1/2. The given point appears to be (-2, 1).

The point-slope form of the equation for a line is ...

  y -k = m(x -h) . . . . . line with slope m through point (h, k)

For the given slope and point, this is ...

  y -1 = 1/2(x +2)

Answer:

approx 216

Step-by-step explanation:

well we go to the 10mm mark and we add the columns taht appear before that. Those are two columns : the brown/orangey one and the green one.

if the scale goes up in twenty and each jump has four squares then we can say that one square is equal to 5 up

so we now can read the first two columns

the first one reads 135

the second one reads approximately 81

we add those up and that becomes 216

so the answer is approximately 216

Answer:

16

Step-by-step explanation:

8/12 ÷ 1/12 = 8/12×24/1=192/12=16

The required number of books that can be fitted to the 8/12 yard long bookshelf is 16 books.

Given that,
A small bookshelf is 8/12 yards long. how many books can fit on the shelf if the width of each book is 1/24 yard is to be determined.

The ratio can be defined as the comparison of the fraction of one quantity towards others. e.g.- water in milk.

here,
The total length of the shelf = 8 / 12 yard
Width of a book = 1 / 24 yard
So the total number of books that can be accumulated on the shelf will be the ratio of the total length of the shelf to the width of a book. So,
Total books = 8 / 12 / {1 / 24]
                    = 8 * 24 / 12
                    = 16

Thus, the required number of books that can be fitted to the 8/12 yard long bookshelf is 16 books.

Answer:

  ? = 8

Step-by-step explanation:

The parallel lines divide the segments proportionally:

  ?/4 = 10/5

  ? = 4(10/5) = 8 . . . . multiply by 4

The missing length is 8.

Answer: A, C, E

Step-by-step explanation:

An undefined slope means the line is vertical (and thus the x-coordinates are constant).

Answer:

$7,500

Step-by-step explanation:

1500/2 750, 750x10=7,500

Answer:

Geometric figure: Straight Line

Slope = 120.000/2.000 = 60.000

x-intercept = 346/-60 = 173/-30 = -5.76667

y-intercept = 346/1 = 346.00000

Step-by-step explanation:

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

y-(-4+60*x+350)=0

Equation of a Straight Line

1.1 Solve y-60x-346 = 0

Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).

"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line y-60x-346 = 0 and calculate its properties

Graph of a Straight Line :

Calculate the Y-Intercept :

Notice that when x = 0 the value of y is 346/1 so this line "cuts" the y axis at y=346.00000

y-intercept = 346/1 = 346.00000

Calculate the X-Intercept :

When y = 0 the value of x is 173/-30 Our line therefore "cuts" the x axis at x=-5.76667

x-intercept = 346/-60 = 173/-30 = -5.76667

Calculate the Slope :

Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 346.000 and for x=2.000, the value of y is 466.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 466.000 - 346.000 = 120.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

Slope = 120.000/2.000 = 60.000

Geometric figure: Straight Line

Slope = 120.000/2.000 = 60.000

x-intercept = 346/-60 = 173/-30 = -5.76667

y-intercept = 346/1 = 346.00000
