Question

Could someone explain to me how to get the equation for slope off of a graph? It would be greatly appreciated:)

Answer 1

Ok so how I get slope if doesn’t mention it
I get two pairs from the graph example (2 and 2) and (4 and 4)
When I get two pairs you do x2- x1/ y2-y1
It looks like this 2-2/4-4
2-2= 0 4-4=0
So the slope is is 0 in this one
I hope that helped and you put the equation like this
Y= Mx+b the m is the slope
I hope that helped

Answer 2

Answer: The equation for slope is m = (y2 - y1) / (x2 - x1)

Explanation:

Let m represent the slope.

Let’s say you have two coordinates fall on a line. (1, 5) and (6, 20).

Plugging this into the formula would look like this: m = (20 - 5) / (6 - 1). Simplify to m = 15 / 5. The slope of this line I made up for this example would be 3, since 15/5 = 3.

This formula works with any pair of coordinates on the same line.
