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.

a = 11 : 4

b = 38

c = 1 for every 6

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
