EOC Practice 4 (Interpreting Linear Functions)

The table shows the altitude, y, in feet of an airplane x minutes after it starts its descent.

Identify and interpret the slope of the linear model that represents the plane's descent over time. (Remember slope formula)

• -10,000; The airplane's altitude decreases 10,000 feet per minute.

• 10,000; The airplane's altitude increases 10,000 feet per minute.

• -2,000; The airplane's altitude decreases 2,000 feet per minute.

• 2,000; The airplane's altitude increases 2,000 feet per minute.

The table shows the altitude, y, in feet of an airplane x minutes after it starts its descent.

Identify and interpret the intercepts of the linear model. Check all that apply.

• The y-intercept is 20. The altitude was 20 feet when the plane started its descent.

• The y-intercept is 40,000. The altitude was 40,000 feet when the plane started its descent.

• The x-intercept is 20. It took 20 minutes to reach the ground

• The x-intercept is 0. The plane is on the ground.

Mark buys a hamster at the local pet store. The cost of hamster and supplies is $35. Hamster food costs $3 per week. The function f(x) = 3x + 35 represents the total cost after x weeks.

Identify and interpret the slope of the linear model that represents the total cost over time.

• $32; The total cost increases by $32 each week.

• $3; The total cost increases by $3 each week.

• $35; The total cost increases by $35 each week.

• $0; The total cost increases by $0 each week.

Mark buys a hamster at the local pet store. The cost of hamster and supplies is $35. Hamster food costs $3 per week. The function f(x) = 3x + 35 represents the total cost after x weeks.

Identify and interpret the y-intercept of the linear model that represents the total cost over time.

• $35; The total cost before purchasing hamster food is $35.

• $38; The total cost after purchasing hamster food is $38.

• $3; The total cost after purchasing hamster food is $3.

• $32; The total cost before purchasing hamster food is $32.
