Question

Bradley is returning home from a place that is 2 kilometers away. The function y = 2,000 − 90x represents Bradley's distance from home in meters, y, in relation to the number of minutes he walks, x. Which statements about this function are true? The function is a linear function. The function is a nonlinear function. The function does not change at a constant rate. The function is an increasing function. The function changes at a constant rate.

Answer 1

Answer:

• The function is a linear function.
• The function changes at a constant rate.

Step-by-step explanation:

The degree of x is 1, so the function is a linear function.

The coefficient of x is -90, a constant rate of change that is negative, so the function is decreasing.
