Solve for a.

a+(−5)=−12
what is the answer?
1.) a = -17
2.) a = -7
3.) a = 7
4.) a = 17

i personally think its
2.) a = -7
but i just want to make sure i am correct : )

21.4 i did it already for s1

step-by-step explanation:

i think the answer is d im not sure

a

step-by-step explanation:

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9
