What is the slope of the line that passes through the given points? (Simplify your answer please)

Find the slope of the line shown in the graph.

The initial weight of a container is 6.2 pounds. As water is added to the container, the weight increases at a rate of 0.6 pounds per minute. Which function models the weight of the container as a function of time?

• f(t)=0.6t+6.2

• f(t)=t+6.8

• f(t)=6.2-0.6t

•                                           f(t)=6.2t+0.6

A ball is launched straight up. The function v(t)=96-32t gives the ball's speed, v, in feet per second, in terms of time, t, in seconds as it reaches its maximum height before falling back to the ground. Which graph shown models the function?

• Graph A

• Graph B

• Graph C

• Graph D

Which equation describes the graph?

• f(x)=-4x-2

• f(x)=-2x+4

• f(x)=4x-2

• f(x)=4x+2

A frozen yogurt store charges based on how many ounces of yogurt, y, a customer puts in their cup. They also charge a flat price for unlimited toppings. The function for the cost of a cup of yogurt with toppings is f(y)=0.37y+1.50. What does the function indicate?

• Each ounce of yogurt decreases the cost by $0.37.

• Each ounce of yogurt increases the cost by $0.37.

• Each ounce of yogurt decreases the cost by $1.50.

• Each ounce of yogurt increases the cost by $1.50.

Karen and Henry each sold food at the fair. The table shows the total number of corn dogs Karen sold at different times of the day. Henry uses the equation h=14t to show the number of hot dogs, h, he has sold after t hours. Which statement about Karen and Henry is true?

• The rate that Henry sells hot dogs is half the rate that Karen sells corn dogs.

• The rate that Henry sells hot dogs is double the rate that Karen sells corn dogs.

• The rate that Karen sells corn dogs is 7 times the rate that Henry sells hot dogs.

• The rate that Karen sells corn dogs is the same as the rate that Henry sells hot dogs.
