Question

Which equation does the graph of the systems of equations solve? (graph attached)

a. 3x + 4 = −2x − 1
b. 3x + 2 = −x + 1
c. 3x + 4 = 2x − 1
d. 3x + 3 = −x + 1

Answer 1

As the only point that two line are equal is in the intersection, put (-1) instad of x. Two result should give you 1

Answer 2

(-1, 1) is the solution
when x = -1 which option is true
