The equation of the line-of-best-fit is in the form “Y-value = SLOPE * X-value + INTERCEPT,” so solving for the “Y-value” is done by multiplying the X-value and SLOPE and then adding the INTERCEPT. NettetExample 6: Write the slope-intercept form of the line with a slope of {3 \over 5} and through the point \left( {5,\, - 2} \right). We have a slope here that is not an integer, i.e. the denominator is other than positive or negative one, \pm 1. In other words, we have a “true” fractional slope.

NettetBelow those values, it reports the 95% confidence interval of the slope and both intercepts. At the bottom of the results page, the slope and intercept are reported again in the form of the equation that defines the best-fit line. You can copy this equation and paste onto a graph, or into a manuscript.
