Margo is going to work with a local carpenter during the summer. Each week she will earn $10.00 plus $2.00 per hour. Which function represents Margo's total earnings if she works x hours in one week?

f ( x ) = 2 x + 10 f\left(x\right)=2x+10 f ( x ) = 2 x + 1 0

f ( x ) = 12 x f\left(x\right)=12x f ( x ) = 1 2 x

f ( x ) = 10 x + 2 f\left(x\right)=10x+2 f ( x ) = 1 0 x + 2

f ( x ) = 2 x + 10 x f\left(x\right)=2x\ +\ 10x f ( x ) = 2 x + 1 0 x

Monica gets on an elevator in a skyscraper. The elevator starts to move at a rate of −20 ft/s. After 6 seconds on the elevator, Monica is 350 feet from the ground floor of the building. Select all that apply.

x represents the time in seconds since Monica got on the elevator.

The y-intercept represents the original height above the ground in feet.

Which of the following is the slope-intercept form of the equation of the line in the graph?

y = − 3 5 x + 3 y=-\frac{3}{5}x+3 y = − 5 3 x + 3

y = − 5 3 x + 3 y=-\frac{5}{3}x+3 y = − 3 5 x + 3

y = − 3 5 x + 5 y=-\frac{3}{5}x+5 y = − 5 3 x + 5

y = − 5 3 x + 5 y=-\frac{5}{3}x+5 y = − 3 5 x + 5

Which ratio does not represent the slope of a line?

Δ x Δ y \frac{\Delta x}{\Delta y} Δ y Δ x

r i s e r u n \frac{rise}{run} r u n r i s e

Δ y Δ x \frac{\Delta y}{\Delta x} Δ x Δ y

v e r t i c a l c h a n g e h o r i z o n t a l c h a n g e \frac{vertical\ change}{horizontal\ change} h o r i z o n t a l c h a n g e v e r t i c a l c h a n g e

For a linear function, which statement about slope and rate of change is true?

The slope is equal to the rate of change.

The slope is greater than the rate of change when the slope is positive.

There is no relationship between slope and rate of change.

Slope and rate of change are related, but more information is needed to describe the relationship.

Which shows the equation of the line 4y = 3(x - 21) written in standard form?

3 x − 4 y = 63 3x-4y=63 3 x − 4 y = 6 3

− 3 x + 4 y = − 63 -3x+4y=-63 − 3 x + 4 y = − 6 3

− 3 x + 4 y = − 21 -3x+4y=-21 − 3 x + 4 y = − 2 1

− 3 x − 4 y = 21 -3x-4y=21 − 3 x − 4 y = 2 1

Which pair of quantities most likely does not show a positive correlation?

The number of cups of milk a person drinks each day and the number of vacation days the person has each year

The age of a baby and the weight of the baby

The length of a car trip and the amount of gas required for the trip

Students’ test scores and the number of hours the students spent studying for the test
