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

01

Given information

The given equations are shown below:

y=-1y=2

02

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, m1=m2=0.

03

Write the conclusion

The lines are parallel.
