What are the rates of change and the initial values to these? if you don't have the answer i'll take an explanation on how to do it

Step-by-step explanation:

So, a coordinate plane is made out of two axis, the x and the y. Through these, we have grid squares on the plane showing points. So, each square would be one point. To find the rate of change, or slope, you would have to use the formula:

y(#2) - y(#1)

= Divided by

x(#2) - y(#1)

This formula will calculate the rate of change. I will do the first one for you as follows.

The first point I would find would be (1,3). 1 space on the X-axis, 3 on the Y-axis.

To write a ordered pair to represent the point on the plane, use the (X,Y).

Then, I'd find the second point.

Following the second point, I would do the equation like so.

y(2) - 3

x(2) - 1

See, I used the first points given as the last X and Y variables in the formula.

Hope this helps you out!
