Question

What is the solution to the system of linear equations graphed below?

(0,3)
(0, -2)
(-2, -2 1/2)
(-2 1/2, -2)

Answer 1

(-2 1/2, -2)

Explanation:

The solution is the point where they intersect.

That is the point where x = -2 1/2 and y = -2.

The value of x is written first in the couplet.

Answer 2

Answer: (0,3), (0, -2), (-2 1/2, -2)

Equations:

y = -2

y = 2x + 3

we see that (-2, -2 1/2) doesn't fall in the line therefore not a solution
