Module 5

An hourglass is turned over with the top part filled with sand. After 3 minutes, there are 855 mL of sand in the top half. After 10 minutes there are 750 mL of sand in the top half.
Which equation represents this situation?

• y = 285x

• y = -10.5x + 900

• y = -15x + 900

• y = 75x

Which graph shows a linear relationship?

What are the slope and y-intercept of the relationship shown in the table?

• slope = 0.05, y-intercept = 1,500

• slope = 0.5, y-intercept = 1,500

• slope = 0.05, y-intercept = 2,000

• slope = 0.5, y-intercept = 2,000

Franklin's faucet was leaking, so he put a bucket underneath to catch the water. After a while, Franklin started keeping track of how much water was in the bucket. His data is in the table below.

Write the equation for the relationship.

Write the equation of each line in slope-intercept form.

• y = -60x + 10

• y = -10x + 60

• y = 10x + 60

• y = 10x - 60

Write the equation of each linear relationship in slope-intercept form.

• y = 0.35x + 1.5

• y = 0.35x - 1.5

• y = 1.5x + 35

• y = 1.5x + 0.35

Write the equation of the line that connects each set of data points.
