the right answer is first one
You’ll have to adjust the plotting a bit to fit your graph that you have, but this is the main idea.
C is true as g intercept at 5 and f at 4.5
12j + 12 + 3j or 15j + 12. This is because if you use Distributive Property to distribute the 3, then you multiply 3 by all the number inside the parentheses. I have two expressions because once you get get the answer after you use the property, then you can combine like terms, such as 12j and 3j which is 15j. Hope this helps!
