Start at 0 and go back 7 yards for their loss. You are not at -7 on the number line.
Move 12 to the right because of the gain. It takes 7 or those 12 just to get back to zero and you can still move 5 more to the right. You will wind up with a gain of 5 yards. (+5)
Answer: Line 1: (2, 3) , (4, 12)
m = (12 - 3)/(4 - 2) = 9/2 This is the slope of the line
y = (9/2)x + b
3 = (9/2)(2) + b
3 = 9 + b
b = -6
y = (9/2)x - 6
Line 2: (5, 10) , (14,8)
m = (8 - 10)/(14 - 5) = -2/9
this slope is the opposite sign, and inverse of the first equation's slope. Therefore, the line is perpendicular.
y = mx + b
8 = (-2/9)(14) + b
8 = -28/9 + b
11.11 = b
y = (-2/9)x + 11.11
Step-by-step explanation: Hope this helps :)
The answer is
15m^2n + 4/n
Hope that helps, have a nice night or day <4
