Which lines are perpendicular to the line y - 1 = 1 (x+2)? check all that apply
y + 2 = -3(x – 4)
y - 5 = 3(x + 11). y=-3x - 5 / 5
y = 1x-2
3x + y = 7

Solve the system of equations. y= 2x y= x^2 - 15

Another type of subtraction equation is 16-b=7. explain how you would sole this equation then solve it.
