Answer:
We have been given the function:
y = x+95
Whatever value we substitute for x there will be 95 increase in y for each value of x.
Therefore, option D is correct that is systolic blood pressure increase for each year of age is 95 mm Hg per year.
According to model the systolic blood pressure of someone who is 42 years old is
Put x=42 since, x axis represents the age of people in the given function.
y=42 +95 =137
Hence, the blood pressure of 42 years of age of a person is 137 mm Hg.
