Determine if the equations are parallel, perpendicular, or neither. 1) x + y = 8 and y = -x - 1

2) 9x - 6y = -20 and -3y = 2x - 11

3) 2x = 14 + y and 4x + 2y = 10

4) y = -4 and y = 7

Its due ! write an equation in which the quadratic expression 2x^2-2x 12 equals 0. show the expression in factored form and explain what your solutions mean for the equation. show your work.
