-12x + 12 = 4 - 15x + 9

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 slope of the line that contains the points (4,8) and (9,8)? what type of line is it?

What are the solutions to the equation 4x2+3x=24-x
