How long will it take to turn $3000 into $12,000 if you are earning 6.25% interest compounded monthly?

It will take 53 months because 3000 divide by 6.25 = 480 and 12000-3000=900 and 900 divided by 480 = 53

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!
