|dw:1337803506010:dw| let your (2,-9) be (x1,y1) and (4,1) be (x2,y2). Then, substitute the values into the formula shown above. |dw:1337803661371:dw| |dw:1337803745636:dw| |dw:1337803784757:dw| |dw:1337803844053:dw| |dw:1337803872235:dw| y=5x-19 y=mx+c m is gradient (slope). c is the y-intercept. you can compare y=5x-19 and y=mx+c to get your slope and intercept.
