## raebaby420 3 years ago What is the slope of the line which passes through (0, 3) and (0, 5)?

You need to use the slope formula:$\frac{ y _{1} - y _{2} }{ x _{1} - x _{2} }$where your given points are (x1, y1) and (x2, y2). So, x1= 0, y1 = 3, x2 = 0, and y2 = 5. Now, make the substitutions, and if you don't have a "0" in the denominator, you will get a real number answer. If you get a "0" in the denominator, your slope is "undefined" and you have a vertical line connecting the points. Try this now and see what you get. Show your work.

How are you doing with this? What is : 0 - 0 ? @raebaby420 ?

Ok.. so i got 3-5 ----- 0-0 ???????????????

So, that's a zero in the denominator, so you look at my first post and do what you have to do when you have a "0" in the denominator. The answer is already there.
