The answer is A I believe.
At hour 1, the equation must equal 130,
therefore s(1) = 9(1-1) + 130
s(1) = 9(0) + 130
s(1) = 130
then so on when
s(2) = 9(2-1) + 130
s(2) = 139
The table is missing though but you may consider the following calculations :
Y = 1.6 x
for x = 1 minutes
Y = 1.6 laps
for x = 2 minutes
Y = 3.2 laps
for x = 3 minutes
Y = 4.8 laps
That is about right... 2,514 X 2 = 5,028 so he is about 1,000 off. I will leave the rest to you.
Answer:
Slope:
y-intercept: 
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:

Where "m" is the slope and "b" is the y-intercept.
The slope can be found with the following formula:

In this case you can say that:

Knowing this values you can substitute them into the formula and then evaluate, in order to find the slope. This is:

By definition, the line intersects the y-axis when the value of "x" is 0.
Notice in the table that when
, 
Therefore, the y-intercept is:
