No; the lines have unequal slopes.
Step-by-step explanation:
You can see the appropriate answer by plotting the points on a graph. In the attached, the line through the blue points will have a different slope from the line through the red points.
Answer: 95 mm Hg
Step-by-step explanation:
Given: The equation represents the linear model for the data is

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
Hence, The systolic blood pressure of new born baby = 95 mm hg
8x=6x+20
Btw I figures it out x=10
