Question 139194
The y-coordinate of the y-intercept is the value of b in {{{y=mx+b}}}, the x-coordinate of a y-intercept is always 0.  That is because the x-coordinate of ANY point on the y-axis is 0.


Your equation is in standard form, {{{ax+by=c}}}, so all you need to do is solve the equation for y, that is, manipulate the equation by any valid means to isolate the y on the left side of the equation.  Whatever is then on the right side after you have collected like terms if necessary is going to be in the form of {{{mx+b}}}.  Whatever value is in the place of the b is the y-coordinate and the ordered pair describing your intercept point is (0,b).
