The easiest way to think about a problem like that is to make the function first. The standard function for a line is (y-y1)=m(x-x1), where y1 is your y point from the problem, m is the slope, and x1 is the x point.
so by plugging in the known variables you get (y-0) = 4(x-6). now pick some of the x values from the solutions and she if you get the right answer.
y= 4(x-6)
so if you plug in x= 5
you would get y= 4(5-6)
y=-4 so this point is on the line (5, -4)
