- The slope of a least squares regression can be calculated by m = r (SDy/SDx). In this case (where the line is given) you can find the slope by dividing delta y by delta x. So a score difference of 15 (dy) would be divided by a study time of 1 hour (dx), which gives a slope …

- https://support.minitab.com/en-us/minitab/21/help-and-how-to/statistical-modeling/regression/supporting-topics/basics/slope-and-intercept-of-the-regression-line/
- The slope is 0. When x increases by 1, y neither increases or decreases. The y-intercept is -4. Usually, this relationship can be represented by the equation y = b 0 + b 1 x, where b 0 is the y-intercept and b 1 is the slope.
