How much does 1/3×1/3 equal?

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.)

For the equations below which statement is true ? -2x=14 6x=-42

State if the two triangles are congruent. if they are, state how you know?
