Question

Calculate the slope between (-12, 4) and (-14, 3).

Answer 1

(A) The y-intercept of the line is 1.82.

(B) The number of games that could be won after 13 months of practice is 26.

Explanation:

X : Number of Months of Practice

Y : Number of Games Won

(A)The y-intercept of the line is 1.82.

The y-intercept is the average value of the dependent variable, here the number of games won, when the value of the independent variable, here number of months of practice, is 0.

So, a y-intercept of 1.82 indicates that on average 1.82 can be won if the number of months of practice is 0.
