Answer:
slope = =
= 1
y intercept = (0,-1)
We are given that:
x is the age, and
y is the heart rate
It is also given that
Now, we have been given that the person’s theoretical maximum heart rate (in heartbeats per minute) is where x is the person’s age in years.
Therefore, 50% of is
Likewise, 75% of is
Which is the same as The system of linear inequalities that describes the given information is y>120-1/2x (for 50% max heart rate) and y<165-3/4x (for 75%).
Thus, y will lie between these two extremes as:
The graph of the same is attached.
