The given fuctions are:

this means that for the reference it is:

now for the first coordinate it is:

then:

then:

Finally
Answer:
y-y/x-x
1--1/3-4
1+1/3-4
2/-1
= -2
then you plug in with any one of the points
y=mx+b
1= -2(3) + b
1 = -6 + b
b = 1+6
b = 7
so the equation is: y = -2x+7
Answer:
260 yards
332-72 = 260
260+72= 332 (the perimeter)
I think you just subtract 59 and 11 but i could be wrong
