Which choice could be the equation of a line perpendicular to the line represented by this equation? y=5x-2

What are the solutions of the system? solve by graphing. y = x^2 + 3x + 2 y = 2x + 2

Which equation results from adding the equations in this system? x+6y=9 and -x+2y=-15

Will mark determine whether the conjecture is true or false. give a counterexample for any false conjecture. given: points r, s, and t conjecture: r, s, and t are coplanar. a) false; the points do not have to be in a straight line. b) true c) false; the points to not have to form right angles. d) false; one point may not be between the other two.
