Write an equation of the line in slope-intercept form.

Step-by-step explanation:

Equation of a line

The slope-intercept form of a line is:

y=mx+b

Where m is the slope and b is the y-intercept.

Suppose we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated as follows:

Two points are given: (-4,0) (2,2). Calculate the slope:

We'll use the point-slope form of the line:

y-k=m(x-h)

Take the point (2,2):

Operating:

Adding 2:

Operating, we get the slope-intercept form:

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.
