Sid wrapped 8 gifts.
Look at the equation Sid wrote to caclulate the cost to wrap each gift. (6.80 + 7.35) / 8. 6.80 represents the total paid for wrapping paper. 7.35 represents the total amount paid for ribbon. Knowing that information, using the equation, and knowing who Sid wrapped gifts for, we can infer Sid wrapped gifts for 8 cousins.
Finding the slope, you get [4-(-2)]/[-1-2]=6/-3 = -2
Plugging (2,-2) and -2 into the formula y=mx+b, you get that -2=-4+b.
Therefore, b=2, making the equation y = -2x+2
