Question 208176
Were you given a point that is on the line?  You seem to have been given a value y1=5, but I don't know what you were given for x1.  Whatever it was, if the slope was 1/2, use the distributive property to take 1/2 x - 1/2 x1.


Let us know what x1 is, and maybe we can help you finish it.
