Answer:
The value of k is 0.8
Step-by-step explanation:
we have
[tex]y=kx[/tex]
This linear equation represent a direct variation
we have
y=1.2, x=1.5
substitute in the equation
[tex]1.2=1.5k[/tex]
solve for k
divided by 1.5 both sides
[tex]k=1.2/1.5=0.8[/tex]
The linear equation is
[tex]y=0.8x[/tex]
