Graph the line that contains this point (-1,-3) and has a slope of 1/3
1 answer:
When trying to find the point-slope equation of a line you need to pick a point and plug it into the plain equation with your slope.
-3 = 1/3(-1) +b
Multiply your slope with your x
-3 = -1/3 +b
Move the -1/3 to the other side by doing the opposite operation, in this case being addition.
-3 +1/3 = b
-2 2/3 = b
y = 1/3x - 2 2/3

Answer:
$4
Step-by-step explanation:
Discount is a form of consideration in price or amount given to a customer on a sale of goods. It can be deduced from the question that;
The original price of each plant = $x
Number of plants purchased = 20
Price of the number of plants purchased without discount = $20x
Amount paid for the 20 plants with discount = $(20x - 80)
Thus,
The discount on the 20 plants = $80
Discount on each plant =
=
= $4
Discount on each plant = $4
Therefore, each plant was discounted by $4.
