y = 3x2 + 18x + 15

a (-1,0) & (-5,0)
b (5,0) & (6,0)
c (0,-1 & (0,-5)
d (0,5) & (0,6)

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
