Which statement best describes the polynomial

John used linear combination to solve the system of equations shown. he did so by multiplying the first equation by -3 and the second equation by another number to eliminate the x-terms. what number did jonas multiply the second equation by? 4x-6y=23x+5y=11

If y varies directly as x2 and y=6 when x=6, find the constant of variation.
