The slope of the line and the intercept cut by the line with the y-axis are required for the slope-intercept formula. The slope-intercept formula is given by, y = mx + c where, m = slope of the line c = y-intercept of the line Derivation WebThe equation of a straight line can be written as \(y = mx + c\) \(m\) is the gradient. \(c\) is the \(y\)-intercept. To write the equation of a straight line: Work out the gradient. threaded to threadless headset conversion
