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 [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by the formula,
Slope = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Therefore, slope of the line passing through (0, 0) and (2, 4.5) will be,
Slope = [tex]\frac{4.5}{2}[/tex]
= 2.25
Therefore, cost of potatoes is $2.25 per pound.
