Find a slope-intercept form equation for the line through the points (-10,7) and (5,4).

Step-by-step explanation:

(4 - 7)/(5 + 10) = -3/15 = -1/5

y - 4 = -1/5(x - 5)

y - 4 = -1/5x + 1

y = -1/5x + 5

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !
