i think you should think about the question and not look online.
i pretty sure it is
the slope of the line is 60
one point on the line is (40,10)
in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.
in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
the answer would be 44.79
