The scatter plot shows the systolic blood pressure of people of several different ages. the equation represents the linear model for this data. y = x + 95 according to the model, how much does the systolic blood pressure increase for each year of age? a. 1 mm hg per year b. 5 mm hg per year c. 15 mm hg per year d. 95 mm hg per year e. 110 mm hg per year according to the model, what is the systolic blood pressure of someone who is 42 years old? hg

For question 1 the answer is 95 mm Hg per year and for question 2 the answer is approximately 147mm Hg

The equation give to us for the systolic blood pressure is given as y = x + 95. If we look at the graph and the equation there is an increase of 95 mmHg for each value of x which is the age so we can say that an increase of 95mm Hg is recorded. Then for the second part of the question if we again look at the graph we can see that the age is given in x axis and blood pressure in y axis. Value of x at 42 touches the y axis on 147 approximately which is the required blood pressure for given age.
