To express the total exercise time E based on the number of workout routines r using the slope-intercept form y = mx + b:

Slope (m): This represents the increase in exercise time per workout routine. Each routine adds 20 minutes, so m = 20.

Intercept (b): This is the fixed warm-up time, which is 15 minutes.

So, the equation for the total exercise time ...
