Given the points, we can see that as x increases by 4, y decreases by 4, which means the slope is -1. Working backwards from (5, -8), we can decrease x by 5 (and thus increase y by 5, since we're subtracting a negative) and add that to -8 to find the y-intercept = -3
Answer- 16 Explanation- A square has 4 equal sides. This means all sides are the same length. Divide the perimeter by the sides and you get your answer >>> 64 divided by 4 equals 16.
