Answer:
m = -1
Step-by-step explanation:
Find the slope of this line.
x+y=5
y= (-1)x+5
Slope (m) = -1 <-- from y = mx+b
A line parallel to the line will have the slope -1.
Answer: I believe the answer is y= mx + b
Bottom rectangle = 10*7 = 70
Top rectangle = 8*7 = 56
Side rectangle = 6*7 = 42
Side triangle = (1/2)*8*6 = 24
Side triangle = (1/2)*8*6 = 24
--------------------------------------------------
Total surface area = 70+56+42+24+24 = 216
-11y-9=2
-11y=11
y=-1
4[-1]+1
-4+1=-3
-3 is your answer.
