Example Question #2 : Interpret Slope And Intercept Of A Linear Model: Ccss.Math.Content.Hss Id.C.7

Identify the slope of the following line:

Possible Answers:

Correct answer:

Explanation:

This question asks us to analyze the constituent components of a linear equation written in the slope-intercept formula:

This formula provides information about two key parts of a line: the slope and y-intercept.

The slope is commonly defined as rise over run. In other words, it is the change in y-values across points divided by the change in x-values. It is calculated using the following formula:

In this formula, the x- and y-values come from two points from the line written in the following format:

It is important to note that slopes can be positive or negative. A positive slope moves upward from left to right while a negative slope moves downward.

Now, lets solve the problem. We will start by identifying two points on the line.

These two points are:

Now, substitute these numbers into the slope formula.

The slope is positive because the line moves upward from left to right.

We have calculated that the slope of the equation is 13 We can also calculate the slope by using the traditional 'rise over run' definition. If we count blocks on the graph, then we can see that for every 52 blocks that it 'rises', it 'runs' 4 blocks. In other words, the slope increases one block in the x-direction as it increases 13 block in the y-direction; therefore, the slope is 13 (see figure below)

Explanation:

This question asks us to analyze the constituent components of a linear equation written in the slope-intercept formula:

This formula provides information about two key parts of a line: the slope and y-intercept.

m=\textup{slope}

The slope is commonly defined as rise over run. In other words, it is the change in y-values across points divided by the change in x-values. It is calculated using the following formula:

m=\frac{\Delta y}{\Delta x}

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

In this formula, the x- and y-values come from two points from the line written in the following format:

(x,y)

It is important to note that slopes can be positive or negative. A positive slope moves upward from left to right while a negative slope moves downward.

Now, lets solve the problem. We will start by identifying two points on the line.

These two points are:

\left( -2 , -15 \right) and \left( 2 , 53 \right)

Now, substitute these numbers into the slope formula.

\\ \\ m=\frac{y_2-y_1}{x_2-x_1} \\ \\ m=\frac{ 53 - -15 }{ 2 - -2 } \\ \\ m=\frac{ 68 }{ 4 } \\ \\ m= 17.0

The slope is positive because the line moves upward from left to right.

We have calculated that the slope of the equation is 17 We can also calculate the slope by using the traditional 'rise over run' definition. If we count blocks on the graph, then we can see that for every 68 blocks that it 'rises', it 'runs' 4 blocks. In other words, the slope increases one block in the x-direction as it increases 17 block in the y-direction; therefore, the slope is 17 (see figure below)
