Answer 1

$2.25 per pound

Explanation:

Graph attached shows the relation between the weight of the potatoes and cost of potatoes purchased.

Cost of 1 pound of potatoes will be represented by the slope of the given line.

Since slope of a line passing through two points
`(x_1,y_1)` and
`(x_2,y_2)` is given by the formula,

Slope =
`(y_2-y_1)/(x_2-x_1)`

Therefore, slope of the line passing through (0, 0) and (2, 4.5) will be,

Slope =
`(4.5)/(2)`

= 2.25

Therefore, cost of potatoes is $2.25 per pound.
