I need help please hurry

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

Which shows the first equation written in slope-intercept form? 1/2 (2y + 10) = 7x

For the feasibility region shown below find the maximum value of the function p=3x+2y
