Answer:
Just change the b value so it is lower than it already is in y = mx + b so . . .
y = 3x + 1
y = 3x - 10000
y = 3x - 1000000000000000000000000000000000000
I think you get it now. lol
20+ 90 cuz the angle is 90° then subtract 180 cuz there’s a 180° line
Perimeter of a square = 4s = 20ft
s = 20/4 = 5 feet
New length = 5 + 2 = 7 ft
New width = 5 - 1 = 4ft
New perimeter = 2(7 + 4) = 2(11) = 22ft
-4
The number before the variable is the coefficient.
