James takes two data points from the weight and feed cost data set to calculate a slope, or average rate of change. A hamster we
Lesechka [4]

Answer:

The slope of the line between these two points is 1.50.

Step-by-step explanation:

The general form of the regression line is:

y=mx+c

Here,

<em>y</em> = dependent variable

<em>x</em> = independent variable

<em>m</em> = slope

<em>c</em> = intercept.

The formula to compute slope using two-point method is:

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

In this case the dependent variable is the cost per week to feed and independent variable is the weight of the hamster.

The two points are:

(<em>x</em>₁, <em>y</em>₁) = (3, 3.50)

(<em>x</em>₂, <em>y</em>₂) = (4.8, 6.20)

Compute the slope as follows:

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

    =\frac{6.20-3.50}{4.8-3}

    =\frac{2.7}{1.8}

    =1.50

Thus, the slope of the line between these two points is 1.50.
