Answer:
y+10 = 2(x+1)
Step-by-step explanation:
We have two points so we can find the slope
(−1,−10) and (5,2)
m = (y2-y1)/(x2-x1)
= (2- -10)/(5 - -1)
= (2+10)/(5+1)
= 12/6
=2
The point slope form is
y-y1 = m(x-x1)
y - -10 = 2(x--1)
y+10 = 2(x+1)
If we use the other point
y -2 = 2(x-5)

Left border = 8 feet
Lower border =32 feet
Area=128 〖ft〗^2
<u>Explanation </u>
The area is a right triangle.
Let us take the left border to be y feet and the lower border to be x feet
Area=1/2 yx
The cost of fencing would be 4y+x=64.
From this expression x=64-4y
Substituting this value of x in the area we have;
Area=1/2 y(64-4y)
A=32y-2y^2
To get the maximum area of the triangle the first derivative of the area would te equal to zero.
A=32y-2y^2
dA/dy=32-4y=0
4y=32
y=8
Since x=64-4y
x=64-(4×8)=32
The dimensions of the garden are 8 feet by 32 feet.
Since the garden is a right triangle,
Area=1/2×8×32
Area=128 〖ft〗^2

I believe it is opposite angles.. as a rhombus has two pairs, which combined with their 2 pairs of equal segments gives you opposite angles that are equal
