If you are given a graph, how do you find the equation of it ?

Hey there!

That's a very broad question; do you have any specific examples?

For example:
If a graph is just a line, it's possible to use the formulas y=mx+b and y-y1=m(x-x1) from intercepts/points on the graph.
If the graph is a parabola, you can use formulas like ax2+bx+c, (x-a)(x-b) (from x-intercepts), (x-h)2+k (from the vertex of the parabola).
There are plenty more examples but the question is actually so broad it's impossible to cover them all unless you had a specific question in mind

Hope this helps!
