Question

Which point on the graph is the solution to the system of linear equations? -2x=-y+4 x=-2

Answer 1

The solution is (-2, 0)

Explanation:

Re-write -2x=-y+4 x=-2 in column form:

x=-2

-2x=-y+4

Next, substitute -2 for x in the second equation:

-2(-2) = -y + 4, or:

4 = -y + 4. Thus, y must be 0.

The solution is (-2, 0)
