Answer:
y=-3x+6
Step-by-step explanation:
(y2-y1)/(x2-x1)
(0-6) / (2-0)
0-6= -6
2-0= 2
-6/2= -3
slope is -3
so now we have y=-3x+b
in the coordinates (0,6) it means if x is 0 then y is 6. so the y-intercept is 6.
Therefore the equation would be y=-3x+6

Answer:
f(x)=-1/2(x+3)
y=-1/2(x+3)
x=-1/2(y+3)
-1/2(y+3)=x
-1/2y-3/2=x
-y-3=2x
-y=2x+3
y=-2x-3
f^-1(x)=-2x-3
