Answer:
Step-by-step explanation:
For one line to be perpendicular to another, their slopes must multiply to -1. So, we really want the line with slope 
that passes through the point 
.
Recall the point-slope form of a line. If you have a point 
and a slope 
, the line through that point with the given slope is 
. Plugging in our given point and slope gives our line: 
(point-slope form).
We can convert this line to slope-intercept form, the most common form by expanding the right side and adding 
to get 
by itself:
The rate at which his pulse is increasing after 3 minutes is 9.5 beats per minute
<h3>How to determine the beat rate after 3 minutes?</h3>
The given graph shows the curve and the tangent.
From tangent line, we have the following points:
(x,y) = (3,119) and (1,100)
The beat rate (m) at this point is:
So, we have:
Evaluate the differences
Evaluate the quotient
m = 9.5
Hence, the rate at which Sam's pulse is increasing after 3 minutes is 9.5 beats per minute
