"For problems 1 & 2, find the slope of the line passing through the given points." The points are (6,15) and (4,5) for the first problem. I don't want the answer, I want someone to walk me through it!

    Alright. Does this formula sound familiar?

    I substituted those, i switched it to y1-y2 over x1-x2. I got 10 over 2 which simplifies to 5?

    You can do that :) I learned it as y2-y1/x2-x1, but what you did is okay too :)

    So is that all I would have to write for the answer, 5? Or do I have to do anything else? And The second problem is a little different, if you dont mind helping me with that after this :)

    They're just asking about the slope, so that's it. I don't mind helping at all :)

    Thank you! That was more simple than what I thought it'd be! And I will take a picture of number 2 with my phone, it's a graph

    Is the first point (2,5)? I can't see it very well.

    Honestly, i can barely see it! All I can make out is the (5, -1) /:

    I think it's (2,5) xD It's the same process as the last question.

    Just use the y1-y2/x1-x2 formula :)

    For the second problem, I got the answer of -2

    Okay this is the last one, I swear. I havent done slope in two years. I have to do more problems and they're the ones I have trouble with - graphing. But for the problem 3, its "what is an equation of a line with slope 8 and y intercept 10?"

    Np! y=mx+b m is your slope, so now you've got y=8x+b b is your y-intercept, so plug in 10, and what do you get?

    Would I do the y1-y2 over X1-x2?

    that would get your slope. then you plug in one of those coordinates to get your y-intercept :o once you have your slope and y-intercept you have your equation

    I got the slope of 4, is that right? And how do I get y intercept? y=mx+b , would I say y=4x+ A random coordinate?

    -9.. so the equation would be y=4x-9?
