9. If y = kx, where k is a constant, and y = -3
when x = 6, what is the value of x when y = 12?

Hey there! :)

x = -24.

Step-by-step explanation:

Plug in the values to find the value of 'k':

-3 = k(6)

Divide both sides by 6 to solve for 'k':

-3/6 = k

k = -1/2

Plug this into the equation to solve for the value of x when y= 12:

12 = -1/2(x)

Divide both sides by -1/2:

-24 = x

x = -24.

x intercept = (-1,0)   (4,0)
