Question

Find the equation of the circle passing through the points (1,2), (3,-4) and (5,-6)

Answer 1

The slope of a line is a measure of how fast the line "goes up" or "goes down". A large slope means the line goes up or down really fast (a very steep line). Small slopes means the line isn't very steep. A slope of zero means the line has no steepness at all; it is perfectly horizontal.

For lines like these, the slope is always defined as "the change in y over the change in x" or, in equation form:so the answer is

(-3, 1)
