Hello,
y = ax + b where a is the slope
We have A(-4 ; 2) and B(8 ; 5)

→ Slope : 3/2
a: draw a rectangle an label one side 80 and the other 115
b: 1560 Yards
P = a + b + c
P = 72
a = x
b = x + 2
c = x + 4
72 = x + x + 2 + x + 4
72 = 3x + 6
72 - 6 = 3x
66 = 3x
66/3 = x
22 = x
x + 2 = 22 + 2 = 24
x + 4 = 22 + 4 = 26
the sides of ur triangle are : 22,24,26 <==
