Answer:
If this is what your looking for, the answer may be:
-4y + 12
Hope this helps!
y=4x-11 is the correct equation
Answer:
the slope is 
Step-by-step explanation:
Notice that you are given two points to use for the slope calculation:

So we use the formula for the slope of a line given two points:

Yeeeeeeeeeeeweeeeeeeeeeeeeeee
Well it depends what 'v' stands for
well all you need to do is replace the v with the number it stands for. For example if v=2 then the expression would be 4.2(2) - 5 - 6.5(2)
Then you use the order of operations. first you multiply
8.4 - 5 - 13
then you subtract from left to right
8.4 - 5 = 3.4
3.4 - 13 = -13 - 3.4 = -9.4
So IF v=2 (I used 2 as an example, V might not = 2 in your case) then the
answer will be -9.4
I hope this helped you :3
