Question

What is the solution to the system of equations? (Hint: Use Substitution.)

2 lines Line 1: y equals negative 3 x plus 6 Line 2: y equals 9

Answer 1

(-1,9)

Explanation:

y = -3x + 6

y = 9

-3x + 6 = 9

-3x = 3

x = -1

y is already given as 9, but you can solve for y by plugging the x value into y = -3x + 6,

-3(-1) + 6 = 9

(-1,9)
