The range is 327 the maxim subtract the minimum
I think its A!! But im not sure

Let Y be amount of times beat
let X be amount of time in seconds
the slope intercept form is y=mx+b
fill in the variables: y=30x
The correct answer is y=30x
We can model this situation with a linear equation. We know for our problem that the initial point is (0, 25), and the next point is (10, 108.4). To relate those points and find the slope of our linear equation, we are going to use the formula:

. Notice that we know from our points that:

,

,

, and

. So, lets replace those values in our formula to find

:



Now that we have the slope of our linear equation, we can use the point slope formula:

to complete our linear equation:



Or in function notation:

We can conclude that the equation that matches this situation is

.
