ludmilkaskok [199]

Answer:

C and E

Step-by-step explanation:

To solve this problem, let's plug in each coordinates into the equation.

A:

$-3(-3) + 6(6) + 5 = -7$
$9 + 36 + 5 = -7$
$50 = -7$
$50 \neq -7$
A. cannot be the answer, as 50 does not equal -7.

B:

$-3(-2) + 6(0)+5=-7$
$6+0+5=-7$
$11=-7$
$11\neq -7$
B. cannot be the answer, as 11 does not equal -7.

C:

$-3(0) + 6(-2) + 5 = -7$
$0 - 12 + 5 = -7$
$-12 + 5 = -7$
$-7 = -7$
C. can be the answer, as -7 does equal -7.

D:

$-3(6)+6(-3)+5=-7$
$-18-18+5=-7$
$-36+5=-7$
$-31\neq -7$
D. cannot be the answer, as -31 does not equal -7.

E:

$-3(8) + 6(2) + 5 = -7$
$-24 + 12 + 5 = -7$
$-12 + 5 = -7$
$-7 = -7$
E. can be the answer, as -7 does equal -7.
