The equation of a line with an undefined slope is x = a.
you say undefined
undefined slope is vertical. the equation of a vertical line is x=a , where a is the x intercept
You don't, because it is undefined.
If the slope is undefined, it is a vertical line. Therefore the equation is x=2.
x = 1 (the line intersects the x-axis at 1, and is parallel to the y-axis)We cannot write the equation on the Slope-intercept form, since the slope of the line is undefined. 1 is the x-coordinate of any point on the given line.
Because of undefined slope, because undefined slope does not have a slope it doesn't have anything to substitute for m in the point slope equation.
Given two points, P = (a,b) and Q = (c,d) then provided a â‰ c, slope = (d - b)/(c - a). If a = c then the slope is undefined.
We usually denote the slope of a line as M. Horizontal lines have a slope of zero. Mhorizontal line = 0 Verticle lines have a slope that is undefined. Note that the slope is not infinite, but is undefined. Mvertical line = undefined To write the equation of a horizontal or vertical line, we need to know if it's going to be a slope-intercept form or a point-slope form.
Undefined slopes belong to lines that are vertical. These lines do not cross the y-axis, but do cross the x-axis. Therefore, the equation for these lines are always: x = # (where # is the value at which the line is crossing the x-axis).
An undefined slope is just a line straight down. The slope is undefined.
