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
