Answer:
y=2x-7
Step-by-step explanation:
y-y1=m(x-x1)
y-3=2(x-5)
y=2x-10+3
y=2x-7

Answer:
what are we supposed to solve
Let y=f(x)
y=sqrt(10-3x)
you want to make x the subject
square both sides
y²=10-3x
3x=10-y²
x=(10-y²)/3
now replace y with x
f^-1(x)=(10-x²)/3
Move decimal to the left to form a new # from 1-10
Determine the exponent
Then put it done
