Answer:
The answer to your question is the second option
Explanation:
You can find that they vary directly if you graph the points and obtain a line.
I did it, and a line was the result.
k = (12 - 4)/ (6 -2)
k = 8 / 4
k = 2
Equation
y - y1 = m(x - x1)
y -4 = 2(x - 2)
y -4 = 2x - 4
y = 2x - 4 + 4
y = 2x
