Aug 11, 2009 · b0 - This is the intercept of the regression line with the y-axis. In otherwords it is the value of Y if the value of X = 0. Y-hat = b0 + b1(x) - This is the sample regression line. You must calculate b0 & b1 to create this line. Y-hat stands for the predicted value of Y, and it can be obtained by plugging an individual value of x into the ...

To graph a linear equation in slope-intercept form, we can use the information given by that form. For example, y=2x+3 tells us that the slope of the line is 2 and the y-intercept is at (0,3). This gives us one point the line goes through, and the direction we should continue from that point to draw the entire line.

•Slope of a line •Intercepts •y = mx+b •Applications. x- and y-intercepts of an equation. Definition In the graph of any equation of two variables, the points where the graph of an equation crosses the x-axis are called the x-intercepts and the points where the graph crosses the y-axis are called the y-intercepts

3. Suppose you are given the slope and y-intercept of a line. You can find an equation of the line by substituting these values into the slope-intercept form of the equation. For example, if the slope of a line is 3 2 − and its y-intercept is 14, an equation of the line is y = 3 2 − x + 14. The standard form of this equation is 2x + 3y = 42.

The algorithm to determine whether to label every grid line, every other line, etc. is improved. The semi-log plot now has a wider margin so the y-axis labels fit better. Fixed a bug that sometimes occured when shading a region bounded by an implicit function.
