Graph the direct variation y=-1.5x. Using the graph, find:

The value of x when y=-3; 4.5; 6

When y = - 3, x = ?

When y = 4.5, x = ?

When y = 6, x = ?

Y=-3

-3=-1.5x

you substitiue y value, then you divide both sides by - 1.5 and you get 2 for x.

(2,-3)

y=4.5

4.5=-1.5x

you substitute y value, then again you divide both sides by - 1.5 and you get 3.

(3,4.5)

y=6

6=-1.5x

same thing for this last one. then once again divide by - 1.5 and you get - 4.

(-4,6)
