Answer:</h2>
<u>Ques 1)</u>
Horizontal line: y=1
<u>Ques 2)</u>
Vertical Line: x=1
<h2>
Step-by-step explanation:</h2>
We know that a horizontal line is a line that passes through a point such that the value of y is fixed for such a line.
Hence, if a horizontal line passes through (a,b) then the equation of line is:
y=b
Similarly a vertical line is a line that passes through a point such that the value of x is fixed for such a line.
Hence, if a vertical line passes through (a,b) then the equation of line is:
x=a
<u>Ques 1)</u>
The horizontal line passes through the point (-5, 1).
Hence, the equation of the horizontal line is:
y= 1.
<u>Ques 2)</u>
The vertical line passes through the point (1,-1).
Hence, the equation of the vertical line is:
x=1
