Analysis of the data from 25 mothers indicates that an infant's birth weight (g), y, can be estimated by a mother's weight (kg), x, using the regression equation y = 31 x + 1501. If a mother's weight is 70 kg, the infant's birth weight can be estimated as

If a mother's weight is 70 kg, the infant's birth weight can be estimated as 3671g = 3.671kg.

Step-by-step explanation:

We have that

In this proble, we have that:

So

If a mother's weight is 70 kg, the infant's birth weight can be estimated as 3671g = 3.671kg.

y = - 6

step-by-step explanation:

given the point (- 2, y) lies on the graph then it is a solution of it's equation.

substitute x = - 2 into the equation for value of y

y = 3(- 2) = 3 × - 2 = - 6

the point on the graph is (- 2, 6)
