Best ResponseYou've already chosen the best response.0Call point (5, 4) = (x1, y1), and call point (2, 0) = (x2, y2) Slope = m = (y2  y1)/(x2  x1) The equation of the line is: y  y1 = m(x  x1)

Best ResponseYou've already chosen the best response.0You can leave it as 8/7. Your solution is also correct, but it's not usually left with a mixed numeral.
