A line passes through point (8, 2) and has a slope of -3/4

Write an equation in Ax+By=C form for this line.
Use integers for A, B, and C.

Monica build a remote control toy airplane for science project to test the plane she launched it from the top of a building the plane travel a horizontal distance of 50 feet before landing on the ground a quadratic function which models the height of the plane in feet relative to the ground at a horizontal distance of x feet from the building is shown

A. 90 degrees b. 45 degrees c. 30 degrees d. 120 degrees

Using elimination, what is -4x+2y=-12 4x+8y=-24
