Chapter 3: Q. 138 (page 278)

In the following exercise, use slopes and y-intercepts to determine if the lines are parallel, perpendicular, or neither.

x=-3;x=-2

Short Answer

Expert verified

The given lines are parallel.

Step by step solution

01

Step 1. Given information

The given equations are x=-3andx=-2.

02

Step 2. Determine slope and x- intercept.

  • Since the given lines are vertical, their slopes are undefined.
  • The given lines cut the x- axis at x=-3and x=-2. So, the x-intercepts are -3,0and -2,0.
03

Step 4. Conclusion

The lines are vertical and have different x-intercepts, so, the given lines are parallel.
