Hints:
Intercepts could mean either x-intercept or y-intercept.
3 zeroes means three x-intercepts.
First you would have to isolate y.
3x - 3y = 18 -----> Subtract 3x from both sides
-3y = -3x + 18 --------> Now divide both sides by -3
y= x - 6
Now you replace the y with an f(x)
f(x) = x - 6
PEMDAS
100 times 7 is 700
678 times 56 is 37968
700 +8 - 37968
-37260

Suppose the original function is 
To shift it 2 units right, replace x by x-2 such that

So, the function becomes
