(x,y) is a solution to an eqn when y = mx + c
A. 2(2)-1 = 3 <>-1
B. 2+3 = 5<>-1
C. 2-3 = -1 = y
so C has (2,-1) as a solution

The number of songs that Deante' would have downloaded during month 9 is 58 songs.
<h3>What is a regression line?</h3>
A regression line is a statistical line that best describes the behavior of a data set and such, it is a line that best fits a set of data.
By using Microsoft excel to plot the data on a scatter plot, we can logically deduce that line of best fit for the songs downloaded is given by:
y = 2.03x + 39.7
Thus, the number of songs that Deante' would have downloaded during month 9 is:
y = 2.03(9) + 39.7
y = 18.27 + 39.7
y = 57.97 ≈ 58 songs.
