Question

What is the solution to the system of equations

graphed below?
y = -2x-3
y = 3x + 2
O A. (-1,-1)
O B. (0, -3)
O C. (0, 2)
O D. (-1, 1)
XX3

Answer 1

A (-1, -1)

Explanation:

y = - 2 x - 3

y = 3 x + 2

Subtract the first equation from the second equation. we get

0 = 5 x + 5

So x = -1.

Substitute this in the first equation to get

y = -2 * -1 - 3 = -1.
