Question

Choose the equation of the horizontal line that passes through the point (-5, 1).

y = -5

x = 1

y = 1

x = -5


[4_05]Choose the equation of the vertical line passing through the point (1, -1).

x = 1

y = 1

x = -1

y = -1

Answer 1

Q. 1 is y=1 passes through that point
Q.2 is x= 1

Answer 2

Ques 1)

Horizontal line: y=1

Ques 2)

Vertical Line: x=1

Explanation:

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

Ques 1)

The horizontal line passes through the point (-5, 1).

Hence, the equation of the horizontal line is:

y= 1.

Ques 2)

The vertical line passes through the point (1,-1).

Hence, the equation of the vertical line is:

x=1
