How many subsets of {a, b, c, d, e, f, h, i} are there?​

Hope it will be help full , plz brain-list if u found it help full

Step-by-step explanation:

As given equation ,

4x+y=6x-1

2x-1=y or  y=2x-1

By slope intercept method ,

putt the x=0 to find the y intercept (the point where it intersect y axis)

we get  

putt y=0 to find x intercept (the point where it intersect x axis)

we get

0=2x-1

x=1/2
