For a horizontal line, the slope is zero. Using the formula y=mx+b, where m is the slope.

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.

It is the equation of a straight line plotted on the Cartesian plane.

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.

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.

m = (y2 - y1) / (x2 - x1)

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

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.
