Now consider the x-intercept. To find the slope you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points. The graph of f is perpendicular to the.
Identify the values ofx 1x_1 x1 x start subscript 1 end subscriptx 2x_2 x2 x start subscript 2.
So the x-intercept is - y-interceptslope. The SLOPE equation to find out the slope of the linear regression-line is as follows. To find the slope you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points. The formula for the slope of the straight line going through the points X 1 Y 1 and X 2 Y 2 is given by.
