Question

Solve the system of equations by graphing. y=-2x+1 y=-5x+4

Answer 1

(1,-1)

Explanation:

You would graph y=-2x+1 by starting the graph at (0,1) then placing another point at (-1, 3) and drawing a straight line through those points. You would graph y=-5x+4 by starting the graph at (0,4) then placing another point at (-1, 9) and drawing a straight line through those points. The answer would be where the two graphs intersect which is (1,-1).
