The graph of which function has a y-intercept of 3?

Can't see all the options, but all you need to do is look for where the line crosses the y-axis at positive 3.

I am assuming if the question is asking for a positive 3 it is the first graph, if it's asking for a negative 3 then the second paragraph.

Step-by-step explanation:

Whichever graph has a line that goes through 3 on the y-axis is the answer (horizontal line). If the question is asking for a negative 3 then it would be whichever graph has a line going through negative 3 on the y-axis. Hope this helps :)

i believe it is c.y = 9x

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