Hi. How would I enter

F(X)= -6 2/3 X + 7

(Negative 6 and 2 thirds)

Then graph it?

I tried the fraction conversion key but doesn't seem to help me enter fractions as part of the function definition.

(-6 + 2/3) * X + 7

(-6 + 2/3) * X + 7

Ok thanks. I thought there might be a better way. I did it like you said, using () to explicitly define the orders. A bit more awkward than I expected but worked.
Careful folks, -62/3 is going to be either -(6 + 2 / 3) or (-6 - 2 / 3)!!!

What better way? Generally mixed fractions (values) are not supported. Han showed how to efficiently enter a mixed fraction for a value. Any where.
So I see that -20/3 is needed and enter that.
