    first you should graph it so you can find what point is on the y intercept

    right so what is your y intercept on the graph?

    because to do it algebraically you want to put it into slope-intercept form which is y=mx+b m being your slope and b be ing your y-intercept

    ok so your answer is y=3/5x-3

    this means that (0,-3) is the y intercept and if you use your slope you can graph it by going over 3and up 5 for each point.. make sense?

    yes that makes sense... however, is there a way to find this using math like a formula?

    i have another question... what happens if you cant find a y intercept. as in the line is in between the coordinates. i cant determine the intercept like i think it would be a fraction or something

    well there is always going to be a y intercept and it very well can be a fraction
