1. a right triangle is graphed on a coordinate plane. find the length of the hypotenuse. round your answer to the nearest tenth. 2. use the angle relationship in the figure below to solve for the value of x. assume that lines a and b are parallel and line c is a transversal.

Solve the given system of equations. 2y= -x+9 , 3x-6= -15

Just tell me how to set up the equation.
