Answer:

-7, then -13, then -19

Step-by-step explanation:

Plug in x values to get y.

y = -2(0) - 7

y = 0 - 7

y = -7

y = -2(3) - 7

y = -6 - 7

y = -13

y = -2(6) - 7

y = -12 - 7

y = -19

Hope this helps. :0)

_______________

Solve the incomplete quadratic equation:

$\mathsf{3m^2-24m=0}\\\\ \mathsf{3m\cdot m-3m\cdot 8=0}\\\\ \mathsf{3m\cdot (m-8)=0}\\\\ \begin{array}{rcl} \mathsf{3m=0}&~\textsf{ or }~&\mathsf{m-8=0}\\\\ \mathsf{m=0}&~\textsf{ or }~&\mathsf{m=8} \end{array}$

Solution set: S = {0, 8}.

I hope this helps. =)
