Answer: When y = −3, x =2
When y = 4.5, x =-3
When y = 6, x = -4
Step-by-step explanation:
Given equation: [tex]y=-1.5x[/tex]
To find x divide both sides by -1.5 , we get
[tex]x=\frac{y}{-1.5}[/tex]
When y = −3, [tex]x=\frac{-3}{-1.5}\\\Rightarrow\ x=2[/tex]
When y = 4.5, [tex]x=\frac{4.5}{-1.5}\\\Rightarrow\ x=-3[/tex]
When y = 6, [tex]x=\frac{6}{-1.5}\\\Rightarrow\ x=-4[/tex]
So we have points to plot the line to show direct variation on graph as below.
(2,-3), (-3,4.5) and (-4,6)
