15 points 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, what is the systolic blood pressure of a newborn? 0 mm hg 55 mm hg 95 mm hg 110 mm hg 160 mm hg

95 mm Hg

Step-by-step explanation:

We can see on the graph that when x=0 (newborn), the graph is at y=95.

Additionally, if we plug 0 in for x in the equation, we have

y = 0+95 = 95

According to this graph the answer should be 0 mm Hg

Hope this helps!

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
