Question

Khan Academy slope from graph !! Please help me I literally do not understand this.

Answer 1

Answer:

To find the slope from any graph, first you need to pick two points on the graph.

Let's say (0,2) and (4,6)

So the easiest way is to start at the first point and see how much you rise over run to get to the next point. Because slope = rise /run. in this example, you start at (0,2) and you go up (rise) 4 from 0 to 4 and run(go right) 4 from 2 to 6. So rise/run = 4/4=1 ad the slope is 1

Answer 2

Example:
1.) Ok, first pick two points on the line!
(,) and (,)
———————————————————
2.) slope formula Y2-Y1/X2-X1= slope
= Y2 = Y1 7-2 = 5
= X2 = X1 4-1 = 3
———————————————————
3.) Slope is 5/3 since it cannot be simplified.

I hope this broke it down a bit and made it more understandable ☺︎︎
