To graph: the equation,
Answer to Problem 18E
Explanation of Solution
Given information:
Calculation:
The above equation can be written in slope intercept form as follows:
In this equation, y is a constant. So, the value of x has no effect on the value of y. Thus, the graph will have a horizontal line passing at
You may substitute any value of x to find the corresponding value of y at that point. Here, the value of x taken is 2 and -2. Therefore, it gives the point at
