18
Step-by-step explanation:
use the distance forumla to detwemine the distance between the points.
-16 = 8x/5......8x/5 is the same as 8/5(x)
-16 = (8/5)x...divide both sides by 8/5
-16 / (8/5) = x
-16 * 5/8 = x
-80/8 = x
-10 = x <===
3/7 * -2 1/5 = (turn ur mixed number into an improper fraction)
3/7 * - 11/5 = (now just multiply straight across)
(3 * -11) / (7 * 5) = -33/35 <====
It can be at least 5.4 feet long since the area of a square is A=s^2. 5.4 times 5.4 is 30
Answer:

y + 1 = -x - 1
y = -x - 2
x + y + 2 = 0 is the solution
