Pablo is riding his bike. The number of revolutions (turns) his wheels make varies directly with the distance he travels. See the graph below.(a) How many revolutions does Pablo make per foot of distance traveled? (b) What is the slope of the graph?

A general line can be written as:

y = a*x + b

Where a is the slope, and b is the y-intercept.

if we know that the line passes through the points (x1, y1) and (x2, y2), the slope will be:

a = (y2 - y1)/(x2 - x1)

In this case, we can see that the line passes through the points (0,0) and (4,2) then the slope will be:

a = (2 - 0)/(4 - 0) = 2

Then the equation is:

y = 2*x + b

And because we have the point (0, 0), we know that the y-intercept is equal to zero, then the equation is:

y = 2*x

This means that Pablo does 2 revolutions per feet, and we already found that the slope of the equation is 2.

he has now walked a total of what?

if i know what this is maybe i can

step-by-step explanation:

is this a dating site too?
