Bill weighs 150 lbs. he wants to gain 2 lbs per week for football season. jamal runs track. he wants to lose weight so he can run faster. jamal weighs 195 lbs and wants to lose 1 lb per week. how many weeks will it take before both of them are the same weight?

10 weeks =   Bill weighs 170
                      Jamal weighs 185

15 weeks Bill weighs 180
                Jamal weighs 180

It will take 15 weeks Hope this helped!

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!
