Let's add

$\\ \tt\hookrightarrow 3x+7+(9x-2)$

Remove brackets

$\\ \tt\hookrightarrow 3x+7+9x-2$

Combine like variables

$\\ \tt\hookrightarrow 3x+9x+7-2$

$\\ \tt\hookrightarrow 12x+5$

4. I NEED HELP ASAP!! PLEASE PUT AND ANSWER AND STEP BY STEP EQUATION!! IF YOU DON'T KNOW THE ANSWER DON'T PUT ANYTHING!!

Answer:

The answer is A (y = 2x - 2)

Step-by-step explanation:

B and D aren't correct because the y-intercept is a positive 2 instead of negative 2 like the graph shown. We're now left with A and C. Go on one point of the graph and count up or down to go on the same y value as the other point. Go left or right and count until you go to the same point. Remember that the slope equation is rise/run. Rise meaning up or down. Run meaning left or right.
