Find the equation of the line between these two points A (0, 8) and B (-4, 0). How do you put x - y = 1 in slope-intercept form? What is slope-intercept form and how do you graph it? Find the equation of the line using the given information. The li...
I have 4 points in a graph and i can find a tendencie line but when i try to find a 4th degree regression line with the parameters m1,m2,m3,m4 and b it turns out to be a very bad aproximation. I am trying to find the right equation in order to find its maximum. Does anyone...
We’re using this formula that we got the Regression equation. Press CTRL + ENTER. We’ll get the Predicted values from this. We’ll find the squared difference between predicted and actual values. Select the cell range E6:E11 and enter this formula: =(C6-D6)^2 Press CTRL + ENTER....
