Question

What is the solution to

y=-3x + 6
y = 9
(-21, 9)
O (9,-21)
• (-1,9)
(9, -1)

Answer 1

(-1,9)

Explanation:

y=-3x + 6

y = 9

We know that y=9

Substitute that into the first equation

9 = -3x+6

Subtract 6 from each side

9-6 = -3x+6-6

3 = -3x

Divide by -3

3/-3 =-3x/3

-1 =x

x=-1, y=9

(-1,9)
