Chapter 4: Q. 359 (page 522)

In the following exercises, use slopes and $y$ -intercepts to determine if the lines are parallel.
$y = - 1; y = 2$

Short Answer

Expert verified

The lines are parallel

Step by step solution

Given information

The given equations are shown below:

$y = - 1 y = 2$

Determine the slope.

When two points have the constant y-value, it means they lie on a horizontal line. The slope of such a line is 0.

Both the equations represent the horizontal lines.

Hence, $m_{1} = m_{2} = 0$ .

Write the conclusion

The lines are parallel.
