Question

Find the slope between (-1, 9) and (2, 3). if you help me right know

Answer 1

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
