Hello!
If lines are parallel, they can extend forever and never touch. If they had different slopes, they would not be parallel and would eventually touch. Therefore, they are the same, and the slope of the red line is also 3/4.
I hope this helps!
Since they are parallel they can never touch. For them never to touch, their slope has to be the same so they rise or decrease at the same exact pace. The slope of the red line is also 3/4.
