Find vector points from line

[WStephens]

Hi there,

Here is a question from my tutorial sheet. I missed the lecture this material was covered in and I can't figure out where to start based solely on the non-annotated lecture notes provided.

Any help is appreciated, thank you

if \(\displaystyle -y = 5\)

then what does \(\displaystyle y\) equal?

Are there any points on the list that have \(\displaystyle y\) at this value?

 

[WStephens]

y = -5

First two points contain -5 in a y position.

So I checked 'true' for the first two options and 'false' for the second two.

wow, I was definitely over thinking that.

Thank you
