8 !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Sorry to disappoint, but none of these answers are correct. All three limits are equal to 7.
Compute the one-sided limits:


Both the one-sided limits agree, so the two-sided limit has the same value,

Y intercept is (0,-7). slope is 2.
Change the function to y=mx+b format first. m=slope and plug in 0 as x to get y intercept.
