4x - 4y + 7 = 15to get it into y-intercept form do this...4x -4x - 4y + 7 - 7 = 15 - 7 - 4x-4y = 8 - 4x-4y / -4 = (8 / -4) + (-4x / -4)y = x + 2you did not give any values to plug in so this is as best an answer i can give
2y = 4x + 4y = 2x + 2
3x=4y-x 4x=4y x=y
9x + 3y + 5z - 5x + 4z - 7y = 4x - 4y + 9z
It is a straight line equation that can be rearranged into slope intercept form as follows:- 4x-4y = -8 -4y = -4x-8 y = x+2 which is now in slope intercept form
