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|

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.
