To identify:
The slope and y -intercept of the line with the given equation. Use the slope and y -intercept to graph the equation.

Answer to Problem 8.22EP
The slope of the line is
Explanation of Solution
Given:
An equation:
Concept used:
The slope-intercept form of equation is
Calculation:
First of all, we will convert our given equation in slope-intercept form as shown below:
Upon looking at our equation, we can see that the value of m is
We will start from drawing the y-intercept of our given line. The y -intercept of our given line is
Since slope of our given line is
Upon graphing our given equation, we will get our required graph as shown below:
