Answer:
Find x if the slope between (7,-9) and (x,-13) is -1/3
slope between two points:
slope = (y2 - y1)/(x2 - x1)
plug the given data from the problem and solve for x:
-1/3 = (-13 - (-9))/(x - 7)
-1/3 = (-13 + 9)/(x - 7)
-1/3 = (-4)/(x - 7)
cross -multiplying:
3(-4) = -1(x-7)
-12 = -x+7
-19 = -x
19 = x
