What are the steps for finding a function rule, if you are given the graph of a function?

First of all you need to find the coordinates of each points in the graph. Second is to find the slope or the rise over run of the graph when it is connected to every points. The third is to apply the formula in solving the function by assigning each value. The formula is Y=MX+B

Abit confused about what you mean, but i think you might be referring to slope intercept form: y = mx + bin that case b, or the y intercept is already given.(0,-1)find the slope by using the formulay2 - y1/x2 - x1the final slope will be 4/2, equivalent to 2.now your equation should look like thisy = 4/2x -1sorry if this didn’t you out!
