Hi I was wondering if someone could please help me understand how to get the slope of a graph, if so you can either explain it down there or just message me please and thank you!?

Question

Hmm, well which graph...straight line or otherwise? :)

Like this one.

Okay so a linear graph (straight line) are easy to calculate

Specifically this one..because you are given points on the line

So, to find the slope...point out to me 2 points that are on this line :)

|dw:1432147541517:dw|

So 2 points on that line are (0,2) and (1,0)

johnweldon1993 · Answer

So we know that slope = rise/run

In order to find the slope...we need how much 'y' changes...and how much 'x' changes

Or in other words..we have 2 points

$$\large (0,2) \rightarrow (x_1, y_1)$$
$$\large (1,0) \rightarrow (x_2, y_2)$$

We find the slope by writing an equation that shows us how much they change...or

$$\large Slope = \frac{y_2 - y_1}{x_2 - x_1}$$
