How do I write a formula that expresses delta y in terms of delta x if the equation is y=1.1x+4.04 and the points are (-1.4,2.5) and (3.1,7.45)?

each side has a different length.  

step-by-step explanation:

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.
