i dont know how to do it with factions someone help??!!!!im gonna fail becuase i dont know how to do ity-9=2/5(x+20
What was the actual question? How to simplify y-9=2/5(x+20 ) ?
I guess the question is finding the equation of a straight line whose slope is 2/5 and which passes through the point (-20, 9).The equation of a straight line passing through a given point (x1, y1) and with a given slope, m, isy - y1 = m(x - x1).In the given problem, x1 = -20, y1=9 and m=2/5.Therefore, the equation of the straight line isy-9 = 2/5[(x+20)]5y-45 = 2x + 405y - 2x = 852x - 5y + 85 = 0 is the required equation.
