so since there are 2 placeholders, the answer are many, but we can make into slope intercept form to make it easier to solve (slope intercept form is y=mx+b)
15x-12y=60 15x-60-15y=0 15x-60=12y 12y=15x-60 divide both sides by 3 4y=5x-20 divide both sides by 4 y=5/4x-5
just put in values for x and get y so exg (x,y) 0,-5 1,-15/4 2,-5/2 3,-5/4 4,0 and so on
