Rosa can paint 1/12 of the room in a hour
Hanna can paint 1/9 of the room in a hour
Together they can paint 1/9+1/12 of the room in a hour or 7/36 of the room
Since they can paint 7/36 of the room in a hour. They paint the whole thing in 36/7 hours.

Mathematics

Step-by-step explanation:

First we should solve this equation given for 'y'

y=4*4-8*2+4

y=16-16+4

y=4

Now we have value of 'y' we can fnd which points have y coordinate with value of 'y'.i.e., 4

(0,4) (-1,0) will be the answer
