Please help Me answer my last question

Answer 1

PLEASE MARK BRAINLIEST!

Answer:

The answers are...

Per (one) calorie burned, Ali runs: 7.5 seconds

How I calculated:

$\frac{1 min}{8cal}=\frac{8cal}{1min}=\frac{1cal}{7.5seconds}$

Slope: 1/8

How I calculated:

$Slope=\frac{rise}{run}$ . The best way to calculate $\frac{rise}{run}$ is to count up and over until you reach an "intersection". An "intersection" is where 2 lines on a graph meet. An example of an intersection is the plot (80, 10). So, when I found the

- counted up 5 minutes

- counted over 40 minutes

- (40, 5) is its own "intersection"

But the slope isn't complete! 5/40 is not the slope. Why? This is because 5/40 can be simplified. So, when we simplify 5/40, we get 1/8. So, our slope is 1/8.

I hope this helps!
