#(7-1)=m(4-(-6))##y# is the y-coordinate of the point on the right. #y_1# is the y-coordinate of the point on the left. #x# is the x-coordinate of the point on the right. #x_1# is the x-coordinate of the point on the left.
#m=(7-1)/(4+6)# m is the gradient, and is the change in y over the change in x.
Therefore, #m=6/10#, dividing top and bottom by 2 gives a simpler fraction: #3/5#
