Step-by-step explanation:
To find the rate of change for the increase (warm up), use the coordinate pair of any two points on the line that slopes upwards in the graph.
Let's use the following:
At 5 mins (x), heart beats (y) is 80 => (5, 80)
At 10 mins (x), heart beats (y) is 100 => (10, 100)
Rate of change =
Rate of change is 4.
I am not sure if this answers your question exactly, but because both equations are equal to "u" than you can equal them to each other.
It would be the last answer because you are setting them equal to each other.
