represents the predicted value of y calculated using the equation = a + bX.

In the formula, SBP () = 65 + 4.2 X; where X = value of postnatal age (hours) for the neonates 1,000 grams?

a. What is the value of the intercept (a)? [ONE POINT]

Answer: 65

b. Interpret the value of the intercept

[ONE POINT]

Answer: The interception is constant, and Y axis is the point where the line crosses the vertical line

c. What is the value of the slope (b)? (ONE POINT)

Answer: 4.2

d. Interpret the value of the slope? [ONE POINT]

Answer: If the SBP of the neonates by one hour of post-natal age, the SBP will increase approximately at the slope of the line.
