Answer:
y = -1/6x + 2
Step-by-step explanation:
Slope: (-6,3) and (6,1) = (1-3) / (6 - - 6)
= - 2/12 = -1/6
b = 3 - (-1/6)(-6)
b = 3 - 1
b = 2
2(-4y) +7y =3
-8y + 7y =3
-y=3
therefore y= -3
If f(x)=1/9x-2
then f^-1(x) will be
lets assume f(x)=y
y=1/9x-2
y+2=1/9x
9(y+2)=x
f^-1(x)=9(y+2)
rest u can do with the same method
