If the equation is y = -3x+6 and y=9, substitute 9 for y then solve for x.

9 = -3x + 6 (subtract 6 from both sides)
3 = -3x (divide each side by -3)
-1 = x

(-1,9) is the solution.

we have

<u>The system of equations</u>

y=-3x+6 -------> equation 1

y=9 -------> equation 2

Substitute equation 2 in equation 1

9=-3x+6

subtract 6 both sides

9-6=-3x+6-6

3=-3x

Divide by -3 both sides

x=-1

the solution is the point (-1,9)

therefore

the answer is

the solution to the system of equations is the point (-1,9)
