Slope = (Y2 - Y1) / (X2 - X1)
Slope = (5 - 3) / (5 - 8) = 2/-3 = -2/3
Answer: (B) -2/3
Hey there!
You can plug this into the slope equation to find the slope.
m= (y2-y1)/(x2-x1)
Plug in two points. I chose (0,4) and (1,7).
m= (7-4)/(1-0)
m= (3)/(1)
m= 3
3 is your answer.
I hope this helps!

If R represents Reggie's time, the total time for the team is
.. R +(R +2.45) +(R -3.81) = 3R -1.36
.. = 3*57.12 -1.36
.. = 170.00 . . . seconds
