WebTo find the x-intercept we generally just use the same formula 'y=mx+b'. The reason that 'b' is the y-intercept is because at the 'y-axis, x=0'. By this I mean if you look at any graph, for the point a line touches the y-axis, the x-value of a coordinate is always = 0. Knowing this, if you substitute 0 in for x in the formula you get: pond sphereWebOct 6, 2024 · The equation of the line of best fit is y = ax + b.
