write an equation in standard form of the line that passes through the point (-2,7) and has a slope of -1
1 answer:
Step-by-step explanation:
First, sub in the ordered pair to find y int
(7) = -1(-2) + b
7 = 2 + b
b = 5
So the equation in y int form is
y = -1x + 5
This when convert to stardard form is
x + y = 5

The length is 9.
The formula to find the perimeter of a rectangle is
2L + 2W = P.
2L + 2(4) = 26.
2L + 8 = 26.
2L + 8 (-8) = 26 (-8).
2L = 18.
2L/2 = 18/2.
L = 9.
