Point 1: the cost of 4 pencils is $0.80
Point 2: the cost of 5 pencils is $1.00
Explanation:We have been given two points on the graph:
(4, 0.8) and (5, 1)
(x, y) = (number of pencils, cost)
The y-axis represents the cost of the item (pencil). The x-axis represents the number of pencils
Point 1: (4, 8)
when x = 4, y = 0.8
This means the cost of 4 pencils is $0.80
Point 2: (5, 1)
When x = 5, y = 1
This means the cost of 5 pencils is $1.00
