WebThe higher the absolute value, the stronger the relationship. The equation for the covariance (abbreviated “cov”) of the variables x and y is shown below. As a preference of style, we multiply by 1 n − 1 instead of dividing … WebTo isolate y, first subtract 2x from both sides (4y = -2x + 100), then divide by 4 (y = -1/2 x + 25). This is the more common usage because this is a linear function in slope intercept form - y in terms of x or y dependent on x. To solve for x, subtract 4y from both sides (2x = - 4y + 100), then divide by 2 (x = - 2y + 50).
