i believe it's 22.5 out of 45 to get exactly .500
ANSWER:

STEP-BY-STEP EXPLANATION:
We have that the equation in its slope-intercept form is the following:

The slope can be calculated as follows:

We use the points (4,7) and (1,1) to calculate the slope:

Now, we calculate the value of b, using the point (1,1) and the slope, like this:

Therefore, the equation would be:
Answer:
