How do you use slope to graph equations?

answer:

step-by-step explanation:

y = mx + b.

graph the equation: y = 2x + 4.

slope = 2 or 2/1.

y-intercept = 4 or (0,4)

step 1: plot the y-intercept on your graph.

step 2: from the y-intercept (0,4) use the slope to plot your next point.

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 !
