When reflecting over a line, the first step is to Find the slope of the line of reflection.
Find the perpendicular slope.
Count slope triangles to find the distance of the pre-image to the line of reflection.
Flip the pre-image over the line of reflection.

X-intercept=-5 y-intercept=2 the equation of the line is

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