If 20 people in green shirts make up 8% of the people at a meeting, how many people are at the meeting?

20 250 people
--- =
8% 100%

100÷8=12.5
20×12.5=250

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!
