A line on this coordinate plane is horizontal when every input (x) has the same output y).
This function always gives the same output with no matter what input you put it in.

Now multiple the coefficients and add the exponents with common bases

Now write your final expression

Hope I helped!
The 90° CCW transformation is

For your point, this is ...
... (-3, -4) ⇒ (-(-4), -3) = (4, -3)
