Question

Which graph best represents the solution to the following pair of equations?

y = −x − 5
y = 2x + 4

Answer 1

Two lines having equations y is equal to negative x minus 5 and y is equal to 2 times x plus 4 are plotted. These 2 lines intersect at the ordered pair negative 3, negative 2.

Explanation:

Obviously, the appropriate graph will be one with the two lines plotted. Properly plotted, they will intersect at (-3, -2).
