What is the rate of change of y with respect to x, for the table?

• 3

• 4

• 2

• 1

What is the slope of the linear function shown in the table?

What is the slope of the line passing through the coordinates (2,5) and (-5, 5)?

• 0

• 1

• -1

• Undefined

Calculate the slope of the line that contains the points (-3, 8) and (-1, 0).

The graph of a linear function is shown on the grid. What is the rate of change of y with respect to x for this function? NO DECIMALS answer must be in fraction form, NO SPACES.

What is the zero of the linear function graphed on the coordinate grid? Type your answer as a coordinate pair, (x,y), NO SPACES.

Jimmy is hiking down an elevated path. The graph below models the distance he is from the ground, y, after x minutes. What does the x-intercept represent?

• It took Jimmy 18 minutes to hike down the path.

• Jimmy is hiking at a rate of 20 feet per minute.

• Jimmy's initial height is 360 feet above the ground.

• After 12 minutes Jimmy is 120 feet above the ground.
