Question 442281: State whether the statement is TRUE or FALSE.
(a) y = 3x – 1 and y = 2x –1 are parallel.
(b) y = 5x + 6 and 5y = x + 6 have the same y-intercept.
(c) The gradient of 5y = x + 6 is 1/5 .
(d) y = 4 is a horizontal line.
(e) y = 4x goes through the point (4, 1).
(f) x = 4 is a vertical line.
Answer by ilana(307)   (Show Source):
You can put this solution on YOUR website! A is false. The slopes are different (3 and 2).
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.
