B is false. The first has a y-int of 6 and the second has a y-int of 6/5.
C is true. The slope, or gradient, is 1/5.
D is true. If each point has a y-value of 4, the points will lie on a horizontal line.
E is false. When x=4, y=4x, which is 16, not 1.
F is true. If each point has an x-value of 4, the points will lie on a vertical line.
