How To Write Undefined Slope

M represents the slope of the line so if m is positive the slope is positive.

How to write undefined slope. As a vertical line will always make an angle the size of of 90 with the positive direction of the x axis. Since there exist no number you can multiply 0 by to get 3 we say that the slope is undefined. M 4 1 3 3 m 3 0. For 2 5 then x 2 and y 5. Any vertical line like the one shown below will have an undefined slope.

Tan 90 undefined. 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. The slope of a horizontal line is zero. How do you write an undefined slope in standard form. You also know how to identify whether the slope is positive or negative when the line is written in y mx b form.

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. Standard form of linear equations. When you see the slope is undefined then the line is a vertical line or at x a where a is the x intercept. 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. To understand the discussion below you should be familiar with finding the slope using the slope formula.

These lines are always of the form x c where c is some number. An undefined slope means the slope is too large to describe or m is infinity. This is also the case for all the lines above.
