Answer:
New selling price= $14.4
Step-by-step explanation:
Giving the following information:
The store offers a 20% discount. The regular price of a T-shirt is $18.
<u>To calculate the discounted selling price, we need to use the following formula:</u>
New selling price= selling price*(1 - discount rate)
New selling price= 18*(1-0.2)
slope = (y2-y1)/(x2-x1)
m= (-6--5)/(-1--3)
m = (-6+5)/(-1+3)
m=-1/2
