Find the slope of the line. (If an answer is undefined, enter UNDEFINED.)

−4x + 5y = 9

my answer:
−4x + 5y = 9
5y = 4x+9
y=(4/5)x +(9/5)

my teacher never said about converting fractions to decimals and vice versa. does it matter if I put it y=(4/5)x +(9/5) to fractions?

It is in fractions

you could say:

y = (4x + 9)/5, same thing
or
y = 0.8x + 1.8 , it's all the same
