Y-y1=m(x-x1)
m= slope =-3
y-y1=-3(x-x1),
y1=-7, x1=5
y--7=-3(x-5)
y+7=-3(x-5) this is C

For this case we must simplify the following expression:

$(9x ^ 2 + 10x + 4) - (9x ^ 2 + 5x-1)$

We eliminate the parentheses taking into account that:

$- * + = -\\- * - = +\\9x ^ 2 + 10x + 4-9x ^ 2-5x + 1 =$

We add similar terms taking into account that:

Equal signs are added and the same sign is placed.

Different signs are subtracted and the major sign is placed.

$9x ^ 2-9x ^ 2 + 10x-5x + 4 + 1 =\\5x + 5$

Answer:

$5x + 5$
