Why do equivalent ratios form a straight line when graphed?

The vertical distance between points is constant, and the horizontal distance between points increases with each point.

The ratio of the change in y-values to the change in x-values is equivalent for any two points in a graph of equivalent ratios.

The horizontal distance between points is constant, and the vertical distance between points increases with each point.

The y-values of equivalent ratios increase at a constant rate, and the x-values decrease at a constant rate.

Answers

Answer:

D-The y-values of equivalent ratios increase at a constant rate, and the x-values decrease at a constant rate.

Step-by-step explanation:

Answer:

The bicyclist rides (64) miles in (4) hours.

Step-by-step explanation:

As you can see the 64 is on the Distance side, so that shows how far he or she travels.  Then you can see on the bottom of the graph it shows you time in hours. The point is at 4, so he or she travels 64 miles in 4 hours.

Find the value of the x

Answers

Answer:

The answer should be 77, but the triangle in the question seems off. Read the explanation.

Step-by-step explanation:

To find the exterior angle in this problem, you can use the exterior angle theorem.
Interior angle + interior angle = exterior angle
25 + 52 = 77
You can double-check this answer by figuring out the third interior angle.
Since the sum of all the interior angles of a triangle should be 180, you can determine that
25 + 52 + y =180
Y= 103
or, since a straight line is always 180 degrees (Y+X=180)
25+52+(180-x)=180

X= 77
The reason why I think the question looks weird is since 77 is an acute angle, and even though it's the only answer that makes sense in this question, angle X is clearly an obtuse angle, as shown in the picture.

Part A: What is the approximate y-intercept of the line of best fit and what does it represent? (5 points) Part B: Write the equation for the line of best fit in the slope-intercept form and use it to predict the number of matches that could be won after 13 months of practice. Show your work and include the points used to calculate the slope

Answers

Answer:

Well I can't do it if you don not show the graph :(

Step-by-step explanation:

Answer:

Let's actually find the line of best fit...

m=(nΣyx-ΣyΣx)/(nΣx^2-ΣxΣx)

m=(11*836-130*55)/(11*385-3025)

m=2046/1210  

m=93/55

b=(Σy-93Σx/55)/n

b=(55Σy-93Σx)/(55n)

b=(7150-5115)/(55*11)

b=185/55, so the line of best fit is:

y=(93x+185)/55

A)  The approximate y-intercept (the value of y when x=0) is 185/55≈3.36.

Which means that those who do not practice at all will win about 3.36 times

B) y(13)=(93x+185)/55

y(13)≈25.34

So after 13 months of practice one would expect to win about 25.34 times.
