An online DVD rental site charges a monthly membership fee of $10, plus $4 per DVD that is rented. The relationship between the number of DVDs rented and the total charge per month can be expressed with the equation y = 4x + 10, where x is the number of DVDs rented and y is the total charge per month. Find the domain and range if you want to rent no more than 5 DVD's.

• Domain: {x≥0}

  Range: {y≥10}

• Domain: {0,1,2,3,4,5}

  Range:{10,14,18,22,26}

• Domain: {0≤x≤5}

  Range: {10≤y≤22}

• Domain: {1,2,3,4,5}

  Range: {10,14,18,22,26}

Which of the following represents the equation of a line passing through the point (-4, 3) with a slope of -2?

• y = -2x + 11

• y = -2x + 5

• y = -2x - 5

What is the equation in slope-intercept form of the line that passes through the points (-5,-5) and (5,-1) ?

Plumber Paul charges an initial $75 fee plus $32 each hour, h. Which function models the total cost, C, of Plumber Paul making a house visit?

• c = 75 + 32h

• c = -75 + 32h

• c = 75 - 32h
