Step-by-step explanation:

Given: The equation represents the linear model for the data is

$y=x+95$

Since, age is an independent quantity whereas blood pressure is dependent quantity.

Thus, y represents the the systolic blood pressure of people of several different ages (x).

Now, the age of new born baby =0

Substitute x=0 in the equation , we get y=95

Arranging like terms; solve the linear system using eliminationlly - 3x = 18- 3x = -16y + 33

DENIUS [597]

Solution

For this case we can do the following:

11y - 3x = 18

16y -3x = 33

We can multiply the first equation by -1 and we got:

-11y +3x =-18

16y -3x = 33

_______________

16y -11y = 33-18

5y = 15

y= 15/5 = 3

And then solving for x we got

x = -(18 -11*3)/ 3= -15/3 = 5
