Explanation:
Given that y - 4x = 3
Let's rewrite the equation as y = 4x + 3
This is the equation of a straight line with slope 4 and y-intercept 3.
The slope of the line is positive, which means that as x increases, y also increases.
This indicates a positive correlation between x and y.
Furthermore, the slope of the line is 4, which means that for every increase of 1 in x, y increases by 4.
This indicates a perfect positive correlation between x and y, as the change in y is directly proportional to the change in x.
Therefore, the correct answer is option A - perfect positive correlation between x and y.
