A plane descends at a rate of 1,500 feet per minute.  As the plane approaches the airport, it begins its descent from a height of 10,000 feet above the ground.  Which function can be used to find the time in minutes, t, it takes the plane to land? (a)  

• f(t) = 10000t - 1500
• f(t) = 1500t - 10000
• f(t) = 10000 - 1500t
• f(t) = 10000 + 1500t

If you were to graph the line of the equation

-4x + 3y = -9

which of the following statements would be true?

Choose 2 answers.

• The slope intercept form is

  y = 4/3x - 3

• The slope intercept form is

  y = - 4/3x - 3

• The y intercept is -9

• The direction of the graph would be down from left to right

• The direction of the graph would be up from left to right

Which of the following could be the equation of this situation? May have more than one answer choice.

Choose 2.

• y = 5.75x + 27.25

• y = 5.75x + 21.5

• y - 44.50 = 5.75(x - 4)

• y = 17.25x + 21.5
