I hope you are kidding.
You have -2 -> 3 and 8 -> 5 so call x=-2 and y =3 in the first equation and x = 8 and y = 5 in the second.
When you solve that you get m = 1/5 and b = 17 / 5. Now plug in to the first equation.
I have tried finding the form using the y=mx+b formula and i cant figure out how she got x+17/5
Thank you Stefy.
anonimnystefyLegendary Memberb how did you arrive at that answer
Stefy just looked for a formula of the form y = mx + c so that when x = -2, then y = 3, and similarly when x = 8, y = 5.
how did you arrive at that answer
Doesn't matter. I hope we solved the OP's problem.
Which was ... ?
Hmmm... I thought there was another reason.
Good answer, Stefy.
Define a bijection between the sets [-2,8] and [3,5]. Prove your function is actually a bijection.
