The article titled Slope described real-world situations in which the concept of slope is useful.Slope Y-Intercept introduced the concept of the slope y-intercept form of a linear equation. When equations are written in the form ymx b, "m" is the slope and "b" is the y- intercept. "M" in this case is -3 so the slope is -3. "B" is zero (-3x -3x 0) soHow do you find the equation for the line of best fit? There are many ways, but probably you arent in a statistics class, but in an algebra class. b. What is the equation for the line of best fit? c. Predict the grade for a student who studied for 6 hours. d. Could this line go on forever?b. Draw a line of fit for the scatter plot, and write the slope-intercept form of an equation for the line of fit.the slope or gradient of that line, and the constant term "b" determines the point at which the line crosses the y-axis, otherwise known as the y-intercept. Given any set of n data points in the form (xi, yi), according to this method of minimizing the sum of square errors, the line of best fit is The correlation coefficient r is a measure of the how good the line of best fit is to the data.of the slope Em and intercept Eb. Often the relationship between the x and y data is non- linear but of a form that can be easily reduced to one which is linear. Lines of Best Fit: Writing Interpreting Equations (page 1). Example: The table shows the number of calories burned by a student walking around a track. Plug in (x, y) you used to find slope and m (slope) to solve for the y- intercept, b: y 30x b. The trend line that shows the relationship between two sets of data most accurately is called the line of best fit.Draw the line of best and write the equation of the line (slope-intercept form) Eyeball Method.
