Question

(56 points) This table represents the cups of coffee, c, a coffee shop has left after being open for h hours.

When graphed, all of the points in the table lie on the same line.

What is the slope and y-intercept of the line?

Drag and drop the slope and y-intercept into the corresponding boxes.

Answer 1

Step-by-step explanation:

The slope is the ratio of change in number of cups to change in hours:

• m = (288 - 432)/(3 - 0) = - 48

The y-intercept is the number of cups at zero hour:

• b = 432

The line would be:

• c(h) = 432 - 48h
