The recommended maximum target heart rate while you exercise can be determined by your age using the equation
y = -0.852 + 187 where y is the maximum beats per
minute and x is your age in years. Determine the maximum
target heart rate for a person who is 18 years old. Do not round
your answer.

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

8
