Hi Mikk;
Standard form of an equation is...
Ax+By=C, neither A nor B equal zero, and A is greater than zero.
Let's begin by establishing slope.  This is represented as m, and is the change-of-y divided by the change-of-x.
Subtracting a negative number is the same as adding a positive number.
(3,0) is the y-intercept.  This is the value of y when x=0.  Therefore, let's proceed with the slope-intercept form.  This is...
y=mx+b, b is the y-intercept, the value of x when y=0.
Let's convert to standard form.  We will add (8/3)x to both sides...
