Question

When are two distinct non vertical lines parallel

Answer 1

Answer:

Two lines are parallel when they share the same slope.

Step-by-step explanation:

Two lines are parallel when they share the same slope.

The slope-intercept form of the equation of a line is: y=mx + b, where 'm' is the slope and 'b' the y-intercept.

If two equations have the same value for 'm', then those lines are parallel, for example:

y = 3x + 8 (Red line)

y = 3x + 5 (Blue line)

y = 3x - 10 (Green line)

All the equations stated above are parallel, to show that, I'm attaching the graph of the equations :).
