Mark a point at 8 on the y-axis, move upward 2 and right 1, mark the point and draw the line.
Mark a point at 8 on the y-axis, move downward 2 and right 1, mark the point and draw the line.
Mark a point at -2 on the y-axis, move upward 8 and right 1, mark the point and draw the line.
Mark a point at -2 on the y-axis, move downward 8 and right 1, mark the point and draw the line.

Answer 1

The second one.

Answer 2
