How to Tell if a Slope Is Undefined
Also the slope is positive if the line goes up from left to right negative if it goes down from left to right and zero if it is horizontal. If the line has an undefined slope and passes through the point 23 then the equation of the line is x2. Undefined Slope To minus y one which would be six minus two over the change in x x two minus X one which would be one minus one. . The x-coordinate never changes no matter what the y-coordinate is. This leaves the equation as Ax C. You know that a slope is undefined when you see it graphed as a vertical line or when you use the slope formula and get a zero in the denominator. If the road has an undefined slope and passes by the purpose 23 then the equation of the road is x2. Lines with the Same Slope. A line with a slope of zero is a horizontal line. If the slope of a line is undefined then the road is a vertical line so it cant be written in slope-intercept type how
