Answer:

The equation would be #y=-1#.

Explanation:

Since the line is perpendicular to the #y#-axis, it will be a horizontal line that runs through #(6,-1)#.

In this case, the #x#-coordinate doesn't matter; no matter what, if the line is horizontal to the #y#-axis, it will be horizontal, and thus it will be the same value regardless of the #x#-value.

In this case, the #y#-value is #-1# throughout the line.

Answer:

#y=-1#

Explanation:

A line perpendicular to the y axis will be a horizontal line, the equation of any horizontal line is y=b where b is the y-intercept.

In this case the line goes through the point #(x,y) = (6,-1)# so it has a y value of -1 since the line is horizontal that y value must also be the y intercept so the equation is:

#y=-1#
