What could be the intersection of the plane PRS and plane QRS
MrRa [10]
The plane PRS passes through the points P, R and S. So it contains the line RS. Also the plane QRS passes through the points Q, R and S. So it contains the line RS as well. Since both the planes contain the line RS, the line RS must be the intersection of plane PRS and QRS

These are the options<br> (0,-5)<br> (4,-2)<br> (8,2)<br> (-16,-17)<br> (-1,-8)<br> (-40,-34)
Liono4ka [1.6K]
All you need to do is plug in the points!

Here we go:

3(0)- 4(-5)-8

If it equals 12, then it is a point and an answer. 

3(0)- 4(-5)-8= 12 

(0,-5) is a point!

Next one:

3(4)-4(-2)-8

12+8-8
That equals twelve. (4,-2) is an answer as well!

I am going to quickly plug in the rest of the points, since I think you have the idea. 
<span>(8,2)  3(8)-4(2)-8= 8 This is not an answer. 
(-16,-17)  3(-16)-4(-17)-8 = 12 This is answer. 
(-1,-8)      3 (-1)-4(-8)-8= 21 This is not an answer. 
(-40,-34) 3(-40)-4(-34)-8= 8 This is not an answer.
</span>
I hope this helped you!

Brainliest answer is always appreciated!
