Answer:

the desired equation is y = -7x + 48

Explanation:

As we go from (6, 6) to (8, -8), x (the "run") increases by 2 while y (the "rise") increases by 14. Thus, the slope is m = rise/run = -14/2 = -7.

The slope intercept form of the equation of a straight line is y = mx + b. Here we need to find b.

y = mx + b becomes 6 = -7(6) + b, or 48 = b.

Thus, the desired equation is y = -7x + 48
