Tell you what I'll do: I'll show you the work, for two of them.
Then, knowing how to do it, you'll find the answers.
Deal ?
#1). n + (-13) = -12
Remove the parentheses
on the left side: n - 13 = -12
Add 13 to each side: n = 1
================================
#3). -15 + n = 3
Add 15 to each side: n = 18
OK. Look those over, understand how they're done, then TAKE IT !

Answer:
-3
Step-by-step explanation:
/= negative slope; \= positive slope
The y-intercept is 2 because this is where it crosses the y-axis
Then you find the next point that touches the graph on an exact point which is (-2,-4)
So, your points are (0,2) and (-2,-4) then you do the slope formula of y2-y1 divided by x2-x1
-4-2/-2-0 = 3 and because the line is / then it is -3
