Question

Determine the slope of (a) every line that is parallel to the given line and (b) every line 2y-5x+4=0

Answer 1

5/2

Answer 2

Bazinga! All in my head! :D

Answer 3

but here is how I got that:
2y-5x+4=0
2y=5x-4
y = (5/2)x + 2

Because it is in the form y=mx+b, m (the slope) is 5/2.
Parallel lines will have the same slope.

Answer 4

That is what parallel is.

Answer 5

That is awesome. How do I determine the perpendicular line?

Answer 6

Wow, that last response posted way too many times; i apologize, that was not me i promise.
