Plz asap it will be greatly appreciated

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 x-intercept and y-intercept of the equation 2x+1. 2o

What is the solution to this system of equations? y= 2x - 3.5 x - 2y = -14
