Answer:

a=2

Step-by-step explanation:

Please see attached picture for full solution.

Method 1: Substitute x with another number, other than the numbers that you have already tried. Zero is a good number to work with :)

Then, subst. the values of b and c which you have already found into the equation. Then simplify to arrive at your answer.

Method 2: Notice that when you expand the right hand side, only a(x)({x}^{2}) can give you a x^{3}term. Hence, compare the coefficients of {x}^{3} on both sides. This method is quite safe since the value of a won't be affected in case the value of b and c is wrong.

The point-slope form:

y-y_1=m(x-x_1)\\\\m=\dfrac{y_2-y_1}{x_2-x_1}

We have the points (5, -3) and (-2, 9). Substitute:

m=\dfrac{9-(-3)}{-2-5}=\dfrac{12}{-7}=-\dfrac{12}{7}\\\\y-(-3)=-\dfrac{12}{7}(x-5)\\\\\boxed{y+3=-\dfrac{12}{7}(x-5)}
