Answering for the slope of the two points:
-2-4
1-(-1)
-6/2=-3
-3 is the slope
Distance between home and school(on map)=5cm
every 4cm=8km
therefore distance between home and school=
5/4×8 = 1.25×8 = 10km
Edit: 33% is not

, therefore my solution is wrong. The correct answer is 0.33 x 496, which is $163.68
The following is the original solution, which is incorrect.
33% =

. Multiply the bonus of $496 by

to get the solution of

, or 165 and

Therefore the solution is $165.33
No. 4^2 + 8^2 or 16 + 64 is 80, and the hypotenuse, 12 (144) is not 80.
