The line L has equation 7x - 2y + 11 = 0, Find the gradient of l

First rearrange the equation to get 2y = 7x + 11.Then divide through by 2 to get the equation for y: y=7x/2 +11/2Now differentiate with respect to x to find the gradient function: dy/dx=7/2 + 0We have found our gradient and it is 7/2.
