After 2 minutes on a treadmill, Jenny has a heart rate of 82. After 3 minutes she has a heart rate of 86. Assume that there is a linear equation that gives her heart rate h in terms of the treadmill t. Find the equation and use it to predict her heart rate after 10 minutes on the treadmill.

So it looks like her heart rate goes up 4 points every minute.
We need to find out how it was when she started, that's
82 - 8 = 74. So her heart rate after t minutes is
74 + 4t.
