<span>The answer is:
not a dilation because the points of the image are not moved toward the center of dilation proportionally</span>
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
162 plants, if 60% of the plants live you can set it up like this: 60/100 = X/270, to find X, you cross multiply and divide by 100
The x in your equation is 16/5 or 3 1/5 or 3.2 if you want it simplified
