1. The problem asks for the gradients (slopes) of two lines, J and K, given their equations. 2. The general form of a straight line is $y = mx + c$, where $m$ is the gradient (slope) and $c$ is the y-intercept. 3. For line J, the equation is $y = 4x + 1$. Here, the gradient $m = 4$. 4. For line K, the equation is $y = 4x - 8$. Here, the gradient $m = 4$. 5. Both lines have the same gradient of 4, meaning they are parallel and rise 4 units vertically for every 1 unit they move horizontally. Final answers: - Gradient of line J is $4$. - Gradient of line K is $4$.
