Find the equation of the horizontal line that contains the point left parenthesis 4 comma 6 right parenthesis .(4,6). express the equation using either the general form or the slope-intercept form of the equation of a line.

In this question, we have to find the equation of horizontal line that passes through the point (4,6).

To find the equation of horizontal line, we have to check out the y coordinate of the given point .

And in the given point, y coordinate is 6. So the equation of the horizontal line is y=6 .
