Answer: d
(-5,3)(5,7)
Slope = change in y /change in x
M= 7-3/5-(-5)
M= 4/ 10
M=4÷2/5÷2
M=2/5
Your slope is 2/5 in fraction form or 0.4 in decimal form
It would be your first choice, y= 3/5x i believe
See the attached figure to understand the problem
we know that
tan 42°=1950/BO---------> BO=1950/tan 42°-------> BO=2165.69 ft
tan 39.5°=1950/AO---------> AO=1950/tan 39.5°-------> AO=2365.54 ft
AB=AO-BO--------> AB=2365.54 ft-2165.69 ft-------> AB=199.85 ft
the answer is
The runners are 199.85 feet apart
7 1/2
Or
7.5
That's the answer
