Question

Find the direct variation equation of the graph through the points (0, 0) and (1, -2). Write in y=kx form.

a. y = 2x

b. y = -2x

c. y = 1/2 x

d. y = -1/2 x

Answer 1

If y = k x
and (1,-2) is one of the points
then
-2 = k (1)
so
k = -2.
Plug this value of k into y=kx to get your answer.
