Question

Function A: Function B: Function C: y=x+5y=x+5 (4 points) Which function has a negative rate of change (slope)? Which function has the smallest y-intercept? Which function would you want to represent your money earned per hour? Which function would give you the highest initial amount of money?

Answer 1

Function A has a negative rate of change (slope) because it has a negative coefficient in front of the x term.

Function B has the smallest y-intercept because it crosses the y-axis at the point (0,5).

Function C would be ideal to represent money earned per hour because it has a constant rate of change of 1, meaning $1 earned per hour.

Function A would give the highest initial amount of money because it has an initial amount of 10, which is higher than the initial amounts of Functions B and C.
