Equations of linear graphs — practice question
The equation for line L is $y=\frac{x}{5}+3$. The diagram shows lines L and M, the origin O, point A on the x-axis, and point B on the y-axis.
(a)[1]
Write down the gradient for line L.
(b(i))[3]
Line M is parallel to line L. It meets the x-axis at point A and the y-axis at point B. The coordinates of point A are (15,0). Show that the coordinates of point B are (0,-3).
(b(ii))[5]
Line N is the perpendicular bisector of the line joining point A and point B. Line N meets the x-axis at point C. Find the coordinates of point C.
