Answer:
y=-x+5
Step-by-step explanation:
first, let's find the slope of the line (m), using the equation (y2-y1)/(x2-x1)
here are the given points: (4,1) and (8,-3)
label the points:
x1=4
y1=1
x2=8
y2=-3
now substitute into the equation
m=(-3-1)/(8-4)
m=(-4)/4
m=-1
the slope of the line is -1.
Now, use slope-point form, which is y-y1=m(x-x1)
substitute the numbers into the equation
y-1=-1(x-4)
do distributive prop
y-1=-x+4
add 1 to both sides
y=-x+5
the equation of the line is y=-x+5
hope this helps :)

Answer:
$45 more
(but honestly I think I would spend longer mowing their lawns to try and make some more profit)
Step-by-step explanation:
Mr. Smith requires 4 1/2 hours.
Mrs Jones requires 7 1/2 hours.
7 - 4 = 3
3 * 15 = $45
Let the width be x, then length = 4x - 7
Perimeter = 2(length + width)
2(x + 4x - 7) = 46
2(5x - 7) = 46
10x - 14 = 46
10x = 60
x = 6
Therefore, width is 6 and length is 4(6) - 7 = 24 - 7 = 17
