How To Write Undefined Slope

The equation of the line is x 2 a vertical line we note that a line in slope intercept form is given as y mx b where m is the slope and b is the y intercept when x 0 or at point 0 b.

How to write undefined slope. M 4 1 3 3 m 3 0. To understand the discussion below you should be familiar with finding the slope using the slope formula. It has a slope but slope 0 and this makes it different from a vertical line which has a slope that is undefined because you cannot divide 0 over 0 which. This is also the case for all the lines above. A slope can also be found to be undefined with the other formula for finding the gradient m of a straight line m tan θ.

M represents the slope of the line so if m is positive the slope is positive. For 2 5 then x 2 and y 5. How do you write an undefined slope in standard form. 2 5 slope undefined step 1. These lines are always of the form x c where c is some number.

You also know how to identify whether the slope is positive or negative when the line is written in y mx b form. Tan 90 undefined. As a vertical line will always make an angle the size of of 90 with the positive direction of the x axis. When you see the slope is undefined then the line is a vertical line or at x a where a is the x intercept. Since there exist no number you can multiply 0 by to get 3 we say that the slope is undefined.

An undefined slope means the slope is too large to describe or m is infinity. Any vertical line like the one shown below will have an undefined slope. Standard form of linear equations.
