How to calculate equation of a line
Web22 feb. 2024 · SST = SSR + SSE. 1248.55 = 917.4751 + 331.0749. We can also manually calculate the R-squared of the regression model: R-squared = SSR / SST. R-squared = 917.4751 / 1248.55. R-squared = 0.7348. This tells us that 73.48% of the variation in exam scores can be explained by the number of hours studied. Web3 answers. D y = 1 (The y-intercept of a proportional relationship is always 0, but in this case, there is a point on the y-axis where the line intersects and that point is 1 on the y-axis.) Bot. 1 hour ago. No line is shown on a graph, thus the bot's answer is silly. answered by Tammy. 1 hour ago.
