Question 995436: The graph of a linear relationship, that defines y in terms of x, passes through the points (8,2) and (5,−5.23) .
From the point (8,2) x must change -8 to reach a value of x=0.

What is the corresponding change in the value of y for the change in x?
Thank you in advance!

Question is about the use of slope. Find slope and identify numerator and denominator if you can; and apply them.

m=%282-%28-5.23%29%29%2F%288-5%29=%282%2B5.23%29%2F3=7.23%2F3=2.41

Your description From the point (8,2) x must change -8 to reach a value of x=0. means, you may be able to find and use the y-intercept. You can also keep within the use of slope alone.

Vertical change divided by horizontal change, 7.23%2F3=d%2F%28-8%29
d=-19.28-------how much did y change. This is NOT the intercept; it just is how much did y change.
