## Homework Statement

Write the Cartesian equation for the plane containing the point (2,-1,8) and perpendicular to the line [x,y,z] = [1,-2,-3] + s[5,-4,7].

## The Attempt at a Solution

The situation is that I have my Calc. + Vectors exam tomorrow morning and I'm just going through some questions on my old tests. This one has got me completely lost.

Any help to get me started would be appreciated.

In addition, I have a second question that I thought I got correct but it was marked as incorrect so if anyone can tell me what I did wrong, it would be great.

Sketch the plan (was it a typo and not plane?) given by 3x+4y-10=0

I found the x-int to be 10/3 and y-int to be 2.5. I simply connected the two points. What did I do wrong?
