Which graph best represents the line y=-1/5x+2

There is a line with slope 1/a going through the point (a, a²). find the equation of the line perpendicular to this line at this point. (don’t let this problem intimidate you! solve the problem as you would if i’d given you specific values. just use variables instead.)

What is the range of the relation in the table below? x y –2 0 –1 2 0 4 1 2 2 0

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