Will you help me here at the end of my algebra journey?

I took the final today. It seemed insanely easy…and that alone scares me! Until the 15th I have the opportunity to improve my homework scores. Out of 42 lessons (each of which has 10 – 35 questions in it) I have 100% on all but 1, which I have an 80 in. But this one problem is kicking my heiney. Will you help me out one more time guys?

Q: Find the equation of the line that contains the given points. Write the equation in slope-intercept form, if possible.
(1.4,0.9) and (0.6,0.4).

So y=??????

Thanks
