Answer:
I think 1st option is correct
7) So when x=6 then z=72, they are directly proportional, so if I multiply the first with a number, then I have to multiply the second with the same number.
6 becomes 13 (x) /multiplied with about 2.167/
72 becomes 156(y) /multiplied with about 2.167/
8) Inversely proportional, so if I multiply the first with a number, then I have to divide the second with the same number.
6 becomes 13 (x)
2 becomes ~0.92307(y) /round it to the thousandths place and you get 0.923/
The blue line (B)
You can count by going up 2 over 1
You can read the slope of the line directly from the graph:
m = rise/run = 1/1 = 1. Also easily visible is the y-intercept, b = 1.
Thus, this linear function has the equation f(x) = x + 1.
There’s nothing for us to work with so we can’t answer
