No, every line cannot be written in slope - intercept form.

Because the slope of vertical line is undefined.

Line equation in slope - intercept form is , where is slope and is

-intercept.

For instance the vertical line is .

There is no way to write the above equation in slope-intercept form.

No, every line cannot be written in slope-intercept form.

Because no vertical line could be written in slope-intercept form.
