Step-by-step explanation:
I am not sure what the equation really looks like. there is clearly some typo in there.
but let's take it plainly.
the slope is always the factor of x for a clean "y =" function definition.
4x - 2y = 5
-2y = -4x + 5
y = 2x - 5/2
so the slope for the line as I interpreted the original definition is 2.
if the equation is different, you need to adapt the transformation.
remember, the slope is always the factor of x.
