Chapter 1.3, Problem 83AYU

In Problems 73-92, find the slope and y-intercept of each line. Graph the line by hand. Verify your graph using a graphing utility.

$x=-4$

To determine

To find: The slope and $y\text{-intercept}$ of the equation $x=-4$.

Answer to Problem 83AYU

$\text{Slope = undefined}$; no $y\text{-intercept}$

Explanation of Solution

Given:

The equation $x=-4$

Calculation:

The given equation represents a vertical line ($x=a$) which is parallel to $y\text{-axis}$. The slope of the given equation is undefined and has no $y\text{-intercept}$, but $x\text{-intercept}$ is equal to $-4$.
