Question

# Melody starts at her house and rides her bike for 10 minutes to a friend’s house. She stays at her friend’s house for 60 minutes. Sketch a graph that represents this description.

Hint:

### Figure out the slope of the graph with respect to each situation given in the question.

## The correct answer is: Slope is 0 for x = 15 to x = 75

### SOL – Let distance travelled = y

Time taken = x minutes

Acc. to question, Melody starts at her house.

Graph starts from origin, because when time, x = 0, distance, y = 0

Then, she rides her bike for 10 minutes i.e., distance is increasing with time.

Slope is positive for x = 0 to x = 15

Further, she stays at her friend’s house for 60 minutes i.e., time is increasing but distance remains same.

Slope is 0 for x = 15 to x = 75
