A line on a linear graph has the coordinates of 12, 27 and 5, 9.

 

How would I work out the gradient of the line?

 

Thanks

(12, 27)   (5, 9)

 

The gradient  (slope)  =

 

[ subtract the y coordinates in some order ]  / [subtract the x coordinates in the same order ]

 

So we have

 

[ 27 - 9 ]  /  [ 12  - 5 ]  =

 

[ 18 ]  / [ 7 ]  =

 

18 / 7
