Answer

Initially a pool contains 350 gallons of water. A hose is placed in the pool and the water is turned on. The hose adds 5.2 gallons of water per minute. Model the total amount, V, of water in the pool for x, the number of minutes the hose has been on.

A) V(x) = 5.2x B) V(x) = 350x + 5.2 C) V(x) = 5.2x + 350 D) V(x) = -5.2x + 350

C) V(x) = 5.2x + 350

Answer

Answer

A) No, they are not equal. The slope is never the same along the entire line. B) Yes, they are equal. Slopes of lines are always equal along the entire line. C) No, they are not equal. Sometimes the slope is the same along the entire line, but not in this case. D) Yes, they are equal. This is a coincidence. Slopes of lines are not always the same along the entire line.

Find the slope of the line between x = 0 and x = 2. Find the slope of the line between x = 2 and x = 4. Are the slopes the same? Is the slope of every linear function always constant within the function?

B) Yes, they are equal. Slopes of lines are always equal along the entire line.
