Answer:

b=3a+2

Explanation:

Hello

that is a linear function , we have 3 points, first .let´s find the slope

let

P1(2,8), with p1 also we will find the slope-point equation

P2(4,14)


m=(y2-y1)/(x2-x1)\\m=(14-8)/(4-2)\\m=(6)/(2) \\m=3\\\\y-8=3(x-2)\\y=3x-6+8\\y=3x+2\\\\x=a, y=b\\b=3a+2\\

the function we are searching for is b=3a+2

I hope it helps

have a great day
