Question

1.) How could you describe the pair of lines y = 2x – 5 and 4x – 2y = 9: parallel, perpendicular, or neither?

2.) Explain why you chose parallel, perpendicular, or neither in #1.

Answer 1

The lines are parallel, but with slightly different y-intercepts. The lines are y=2x-5 and y=2x-4.5 The lines are parallel but one crosses the y-axis at 5 and one crosses the y-axis at 4.5.
