Question

Find an equation of the plane consisting of all points that are equidistant from (-5, -1, 4) and (-4, -2, 2).

Answer 1

It's been a while since I took calc 3. hopefully this is right :(

first step is to find the midpoint between those two points.
second step is to realize the vector made by your two points are actually the normal to the plane you are looking for.

now you should have a point and vector
