Answer:
A. The increase in the number of pounds a boy gains each year.
Step-by-step explanation:
A medical student is conducting a study to track boys’ weight from age 5 to age 18. The student graphs some data and determines the line of best fit is
y = 1.73x + 80.13 ............ (1)
where x represents the age of the boys and y represents the weight of the boy corresponding to his age.
Therefore, the slope of the equation (1) represents the increase in the number of pounds a boy gains each year. (Answer)

-1 9
Step-by-step explanation:
Given in the question a 2x3 and 3x2 matrix
Since, the column of first matrix and row of second matrix is of equal integer, 3, so we can multiply them.
The resultant matrix will be of 2x2
We will use dot product
1(2) + 3(3) + 1(4) 1(-2) + 3(5) + 1(1)
-2(2) + 1(3) + 0(4) -2(-2) + 1(5) + 0(1)
