I have over 20 missing assignmets for math and i need help can someone help me its 7th grade work

(08.01)consider the following pair of equations: x + y = −2 y = 2x + 10 if the two equations are graphed, at what point do the lines representing the two equations intersect? (−4, 2) (4, 2) (−2, 4) (2, 4)

Polynomial that can be factored as (3x-4)(3x+4)

Ijust need to see how to do this. so you don’t have to answer all of them just a step by step explanation of one.
