Okay so here to find the answer you have to solve for any one by setting them in y=mx+b form
y=-3x+7 x=-2y-16
2y=-x-16 6=-2y-16
x=6 22=-2y
-11=y
Answer: -8
Explanation: the formula to find slope is
y1 - y2/x1 - x2
When you substitute the values in this formula, you get
= 36 - 12/8 - 11
= 24/-3
= -8
Therefore, the slope is -8
<u>Find the diagonal length:</u>
a² + b² = c²
c² = 4² + 6²
c² = 52
c = √52
-
<u>Find the length AB:</u>
a² + b² = c²
c² = (√52)² + 1²
c² = 52 + 1
c² = 53
c = √53
-
Answer: Length AB = √53
It would be 6.66..... repeating
