fredd [130]

Answer:

m = 12.33

Step-by-step explanation:

Given

Ferret:

Weight = 2.1lb

Cost = \$3.40

Labrador Retriever

Weight = 70lb

Cost = \$7.50

Required

Determine the slope

Represent the given as x or y

Taking the weight as explanatory variable;

We have:

x = 2.1; y = 3.4

x = 7.5; y = 70

Slope is calculated as:

m = \frac{y_2 - y_1}{x_2 - x_1}

m = \frac{70 - 3.4}{7.5 -2.1}

m = \frac{66.6}{5.4}

m = 12.33

<em>Hence, the slope is 12.33</em>
