Chapter 4: Q. 354 (page 522)

In the following exercises, use slopes and $y$ -intercepts to determine if the lines are parallel.
$x = - 4; x = - 1$

Short Answer

Expert verified

The lines are parallel

Step by step solution

Given information

The given equation are shown below:

$x = - 4 x = - 1$

Determine the slope.

The slope of a vertical line is undefined.

With a vertical line, this results in a bottom denominator of 0. However, dividing by 0 is something that doesn’t exist in math. Even though the difference in y-coordinate may change, dividing any number by the change in x-coordinate, 0, will result in an undefined slope.

Both the equation forms vertical line.

Here, $m_{1} = m_{2} = Undefined$

Write the conclusion

The lines are parallel.
