GUYS PLEASE HELP I HAVE A QUIZ

The equation is;

y = 15x + 30

where 15 is the rate of change and 30 is the initial value ( the y-intercept or the y-value when x = 0)

Step-by-step explanation:

When we mean the initial value, we simply mean the value of y when x = 0

This simply refer to the fact that we want to calculate the value of the y intercept

Looking at the plot, the y-intercept can be seen at the value of 30 points earned

The rate of change is simply the slope

to get the value of the slope , we simply are to use the slope equation

Mathematically, we have this as;

m = (y2-y1)/(x2-x1)

so, we simply need to select two different points;

These are (2,60) and (6,120)

So we have the slope as;

m = (120-60)/(6-2) = 60/4 = 15 points per pair of shoes purchased

So writing the equation in the slope intercept form, we have;

y = 15x + 30
