Which equation does the graph of the systems of equations solve? 2 linear graphs. They intersect at negative 1, 1
a) 3x + 4 = −2x − 1
b) 3x + 2 = −x + 1
c) 3x + 4 = 2x − 1
d) 3x + 3 = −x + 1

Answers

Aplug in x = -1 to both sides and you get 1 as the answer for both sides.

Answer:aStep-by-step explanation:If the graphs intersect at point (-1,1) we can substitute the equations to determine if the solutions will yield the point of intersection. Lets look at each equation and solve for x and y:[tex]3\cdot(x)+4=-2\cdot(x)-1[/tex][tex]x=-1[/tex]Substitute it into one of the equations:[tex]y=3\cdot(-1)+4=1[/tex]Therefore the equations in choice at intersect at point (-1,1)
