The vector line can also be represented in intercept form y = mx + e for which e is used for the y intercept because of the variable c used in standard form. The variable f is used to show the x intercept. So you can use vectorline.m to get the gradient, vectorline.e to get the y intercept and so on.

let intersect = l1.intersect(l2);

let l1XInt = l1.xIntercept; //or l1.f;
