Isabel graphed the following system of equations. 2x – y = 6 y = -3x + 4 she came up with the solution (2,-2). what were the 3 steps she did to get that solution? (make sure they are in the correct order)

Plot a point at the y-intercept of the following function on the provided graph. 3y=-5x+7 20 points

Y= 4x + 3 y = - 1 4 x - 5 what is the best description for the lines represented by the equations?
