BRainliest plus 50 points Determine whether the lines AB and CD would be parallel, perpendicular, or neither?

A(-5,3) and B(-5, 7)

What is the slope of AB?

C(1, 9) and D(-10, 9)

What is the slope of CD?

What are the lines? (parallel, perpendicular or neither)

Perpendicular

slope Ab = undefined

slope Cd = 0

Step-by-step explanation:

slope AB = undefined, a vertical line has no slope

slope CD = 0 (a horizontal line has no slope)

AB: Undefined

CD: 0

Perpendicular

Step-by-step explanation:

Slope is the change in y over the change in x

(sometimes called "rise over run")

Formula looks like this:

First let's find the slope of AB

Undefined

Then the slope of CD:

0

         If they are parallel they will have the same slope, perpendicular lines have negative reciprocals as the slope, and neither is neither

         Comparing the slope of our lines lead us to know that the two lines are perpendicular because AB is vertically up + down and CD is horizontally right + left

I hope this is correct and helps, have a nice day :D

answer: input the dimensions of the room to be painted. click the button to calculate the amount of paint and man-hours needed for this job.

interior paint coverage depends on the brand of paint used. the coverage amount is listed on the label of the paint can. use this to adjust the values in the paint coverage section below. paint usually is applied at 350 to 400 square feet per gallon (primer at 200 to 300 square feet per gallon).
