Answer:
we know that
To calculate the slope we need to take two points from data in a table
point 1 (x1,y1) and point 2(x2,y2)
The formula to calculate the slope between two points is equal to
substitute the values and solve for m
Step-by-step explanation:
Answer:
Option D
Step-by-step explanation:
See attached image
We have to see how many times 130 fits into 1494.23:

So now we have to multiply this by the amount of time needed for 130 meters:
11.4940*1=11.4940.
So the answer is 11.4940 minutes.
For this case we have that by definition, the equation of a line of the slope-intersection form is given by:

Where:
m: It's the slope
b: It is the cut-off point with the y axis
While the point-slope equation of a line is given by:

Where:
m: It's the slope
It is a point through which the line passes
In this case we have a line through:
(8,4) and (0,2)
Therefore, its slope is:

Its point-slope equation is:

Then, we manipulate the expression to find the equation of the slope-intersection form:

Therefore, the cut-off point with the y-axis is
