Why you're still finding your X and questioning Y she's happy now.
Slope of segment here = 4/8 = 1/2
slope of perp needs to equal -2
midpoint of segment = (3,-1) so include that as a point:
y = -2(x-3)+1
(y- (-1)) = -2(x-3)
Answer:
115ft and 135 ft
Step-by-step explanation:
L - length
W - width
If width is x ft, then length is (x+20)
Put all in perimeter formula
500= 2 times ((x+20)+x)
500= 2 times (x+20)+x)
500=2 times (2x+20)
500=4x+40
4x=500-40
4x=460
x=460/4
So width is 115 ft, then length is 115+20=135 ft
I am going to show you the procedure with any slope (given that you did not write the value of the slope)
general slope value: m
generic point (x1,y1)
Formula: y - y1 = m (x -x1)
y - y1 = mx - mx1
y - mx - y1 + mx1 = 0
x1 = -2 , y1 = -3 =>
y - mx - (-3) + m(- 2) = 0
y - mx + (3 -2m) = 0
Now suppose a value for m. Lets say it is m = 5.
y - 5x + (3 - 2*5) = 0
y - 5x + (3 - 10) = 0
y - 5x + (-7) = 0 and that is the standard form if the slope is 5. Now you can do the same with any slope.
