Answer: y=1,5x-8

Explanation:

At first transform the equation

2x+3y=18

3y= 18-2x

y= 6 - (2/3)x

The linear function has general form, which looks like that:

y=mx+n

perpendicular means that m1*m2=-1

In our case m1= -(2/3) and m2 is unknown

(-2/3)*m2= -1

m2=3/2 so m2=1,5

The line has to go through the point (6,1)

so 1=6*1,5+n

1=9+n

n= -8

so the function looks like that y=1,5x-8
