What is the point-slope formula and how is it used?

Given a straight line with slope m and a point (p,q) on the line, the point-slope formula of the line is (y - q) = m(x - p) It is used to represent a straight line in the Cartesian plane. This allows techniques of algebra to be used in solving problems in geometry.

Do vertical lines always have an slope?

The slope of a vertical line is undefined. It either slants straight up or straight down-- you can not say which. The formula for slope does not work in this case because the denominator is zero.

How can you tell if a slope is zero or undefined?

A slope is 0 if it is a straight horizontal line. A slope is undefined if it is a straight vertical line.

What is Linear and Non-Linear Relationships?

A linear relationship means that the slope of the line is proportional, which means that the line is straight. In contrast to the linear realtionship, the non-linear relationship's slope is not proportional and the line will curved and not straight. Formula of calculating the slope is the difference of y divided by the difference of x.
