Any line of the form y c where c is some real number will have a slope of zero. SCALED The inclination of slope is calculated the same as DEGREE but the z-factor is adjusted for scale. For the line on the left the points are -3 4 and -3 1 Let x 1 -3 y 1 4 and x 2 -3 and y 2 1 m y 1 y 2 x 1 x 2.
Perpendicular lines have slopes that are opposite reciprocals of each other.
The farther you go the faster your ball travels. M tan lim h0 fx 0 h fx 0h. Since there exist no number you can multiply 0 by to get 6 we say that the slope is undefined. Undefined slope if a line y mx b y m x b is vertical.
