Answer 1

Answer:

$2.25 per pound

Step-by-step 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 = $\frac{y_2-y_1}{x_2-x_1}$

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

Slope = $\frac{4.5}{2}$

          = 2.25

Therefore, cost of potatoes is $2.25 per pound.
