7 0

Step-by-step explanation:

Given points

( -3 , -7) and ( 5, 2)

Now slope (m) 

= ( y2 - y1) / ( x2 - x1) 

= ( 2 + 7) / ( 5+ 3)

= 9 / 8

Now the equation of line is 

y - y1 = m ( x - x1) 

y + 7 = 9/8 ( x + 3)

8 ( y + 7) = 9 ( x + 3)

8y + 56 = 9x + 27

9x - 8y +27 - 56= 0

9x - 8y -29 = 0

Which is the required equation

Step-by-step explanation:

To modify the spreadsheet to calculate the total sales revenue we will add a column " sales revenue "

multiply values of column : ( unit sold * unit price ) to get Total sales revenue. then use excel function : ( SUMIF. =sumif(range, criteria, [sum_range] ) to find Total sales revenue

To get the sales revenue ; replace " store identification value" with sales region " column
