the sign on the leading coefficient is positive, so the parabola opens upwards. The y-intercept exists where the x's are equal to 0, so the y-intercept is (0, -8). Match that to the table that has those characteristics in it.

a-b=7
add the two equations using system of equations
2a=20
a=10
10+b=13
b=3
