d Does a line perpendicular to a vertical line have slope 0

(d) Does a line perpendicular to a vertical line have slope 0? 1. Yes 2. No, a line perpendicular to a vertical line will have an undefined slope. 3. No, a line perpendicular to a vertical line will have a positive slope. 4. No, a line perpendicular to a vertical line could be horizontal, vertical, or neither. 5. No, a line perpendicular to a vertical line will have a negative slope.

Solution

correct optin 1. yes. a line perpendicular to vertical line have slope 0.

ex: consider vertical line y-axis.

the line perpendicular to y axis is x axis whose slope is zero 0.

correct answer 1.
