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.

Write an equation that represents the line. (-3,-6) and (2,-2) use exact numbers

Ilia_Sergeevich [38]

Given:

The line passes through (-3,-6) and (2,-2).

To find:

The equation of line.

Solution:

If a line passes through two points $(x_1,y_1)\text{ and }(x_2,y_2)$ , then the equation of line is

$y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)$

The line passes through (-3,-6) and (2,-2). So, the equation of line is

$y-(-6)=\dfrac{-2-(-6)}{2-(-3)}(x-(-3))$

$y+6=\dfrac{-2+6}{2+3}(x+3)$

$y+6=\dfrac{4}{5}(x+3)$

$y+6=\dfrac{4}{5}(x)+\dfrac{4}{5}(3)$

Subtract 6 from both sides.

$y=\dfrac{4}{5}(x)+\dfrac{12}{5}-6$

$y=\dfrac{4}{5}(x)+\dfrac{12-30}{5}$

$y=\dfrac{4}{5}(x)+\dfrac{-18}{5}$

$y=\dfrac{4}{5}(x)-\dfrac{18}{5}$

Therefore, the equation of line is $y=\dfrac{4}{5}(x)-\dfrac{18}{5}$ .
