To write:
An equation of line that has no x -intercept and an equation of line that has no y -intercept. Describe the graph of each equation.
Answer to Problem 27E
The equation
The equation
Explanation of Solution
Calculation:
We know that a horizontal line has no x -intercepts as horizontal lines are parallel to x -axis. The equation of a horizontal line is in form
Let us say that our horizontal line intersects y- axis at point (0,3), so the equation of our line would be
Upon graphing our equation, we will get our required graph as shown below:
We know that a vertical line has no y -intercepts as vertical lines are parallel to y -axis. The equation of a vertical line is in form
Let us say that our vertical line intersects x- axis at point (0,4), so the equation of our line would be
Upon graphing our equation, we will get our required graph as shown below:
