Question

Graph the direct variation y=−1.5x. Using the graph, find the value of y corresponding to the value of x equal to 1; 0; 2; 3.

Answer 1

X=1
y=-1.5(1)
y=-1.5
(1,-1.5)

x=0
y=-1.5(0)
y=0
(0,0)

x=2
y=-1.5(2)
y=-3
(2,-3)

x=3
y=-1.5(3)
y=-4.5
(3,-4.5)

all you do is substitute the x value in the equation to get y
