    use m=(y2-y1)/(x2-x1)

    Slope is the rise over the run. How many units up (or down) does the line go when you move 1 unit right or left? Formula: \[m= \frac{(y_2-y_1)}{(x_2-x_1)}\] where \((x_1,y_1), (x_2,y_2)\) are the points.

    I did. But i'm not sure if my answer is correct...

    I'll give you a hint: look at the y-values.

    the answer is 0 because 0/4 can't be 4

    0 divided by 4 is 4?

    Oh okay. I see. So the answer to that problem is 0 then?

    How does that work though? Can you please show me?

    Yes. That's why I suggested looking at the y values. If the y values are identical, the line is horizontal. If the x values are identical, the line is vertical.

    It's good to have an intuitive understanding of what slope means. Positive slope means it goes up as you move to the right. Negative slope means it goes down as you move to the right. Slope > 1 means it goes up more than 1 unit for every unit you move on the x axis. Slope < 1 (but > 0) means it goes up less than 1 unit for every unit you move on the x axis.

    what is the slope of the line that passes through (-3,2) and (1,2)? so to this problem...my answer is going to be 0 then?

    Yes, the answer is 0. The line is horizontal, because for each point, the y value is the same.

    It's really worth practicing finding the slope and seeing what different slopes look like; having a feel for that will save you time and prevent wrong answers in the future. Use a pair of dice to make up points, plot lines between them, and find the slope.
