From the question, we need to find a line with slope (m) = 1/4, and that passes through the point (0.2, 4/5).
We can use, in this case, the Point-Slope Form of the line, that is:
Then, we have:
x1 = 0.2
y1 = 4/5
Thus, we finally have:
We multiply the fraction 4/5 by 4/4 (4/4 = 1) to sum fractions with the same denominator because it is easier to do this in this kind of operation.
Then, the final equation is:
