Answer:
Step-by-step explanation:
Let
L ----> the length of the rectangular garden in feet
w ---> the width of the rectangular garden in feet
step 1
Find the width
we know that
The perimeter of the rectangular garden is
so
Simplify
----> equation A
----> equation B
substitute equation B in equation A and solve for W
Find the value of L
step 2
Find the area
we know that
The area of the rectangular garden is
substitute the values
Assuming you want the equation in slope intercept form, you first need to use slope formula to find the slope.
Plug in the coordinates that you have, (3,-1) and (4,7), for the x and y values respectively.
Which reduces to 8/1=8.
The slope of your equation is 8.
Slope intercept form is: y=mx+b. m is your slope and b is your y-intercept, x and y stay unchanged.
Plug the slope in:
y=8x+b.
Now, you can plug one of the sets of coordinates into the x and y of the equation to find b. I'm using (3,-1).
-1=8(3)+b
-1=24+b
Subtract 24 from both sides.
-25=b
Now plug this into the equation!
y=8x-25 is your final equation.
I hope this helps :)
