Parallel and Perpendicular lines?
I need help w/ these two questions.
8.Use the given info. to write the equation of each line
b)a line perpendicular to the line defined by y=3x+5 and passing through the points 3,-5
12. Show algebraically that the points A(-4,7), B(6.5,1), C (-8,0) and D(2.5,-6) form a rectangle.

12x + 4y = sixteen 4y = sixteen - 12x y = -3x + 4 slope m1 = -3 (y = mx + c) 5y - 22 = -15x y = -3x + 22/5 slope m2 = -3 subsequently, the two strains are parallel to one yet another on condition that they have comparable slope
sorry i don not know this math. i hope you can figure out the answer, good luck!
