How do you turn y=2/5x-6 into coordinates

i know it turns into {(15,0), (10,-2), (-5,-8), (-10, -10)} but Im not sure how to get there... please help!!-you just need to plug the x values into the equation to find if it is true or not. For ex

Find a formula for the nth term of the following sequences:
