Question

Which equation in point-slope from is equivalent to y=-3/4x + 9?

A. y-9=-3/4(x-0)
B. y-1=-3/4(x-9)
C. y-3/4=9(x-0)
D. y-1=9(x+3/4)

Answer 1

Explanation:

I know that in point-slope form, the equation is y - y1 = m(x - x1)

Fill in y1 and x1 with the points given in the multiple choices.

If you look at Letter A, it shows the point (0,9). If you fill that in the formula. You solve the equation:

y - 9 = -3/4(x - 0)

y - 9 = -3/4x

+9. =. +9

y = -3/4x + 9

Therefore your answer is letter A.
