The true statements are;
A. Line 4y = −16 is horizontal.
B. Line 3x = 27 is vertical.
C. For both lines, all points on the line have an x- and a y-coordinate.
D. For either line, one of the coordinates of all the points is always the same value.
For the line 4y = −16, the line can also be written as;
y = -4.
This means that the line 4y = -16 is a horizontal line which has a point with coordinate, (0,-4) on it.
For the line 3x = 27, the line can also be written as;
y = 9.
This means that the line 3x = 27 is a vertical line which has a point with coordinate, (9,0) on it.
Also, for both lines, all points on the line have an x- and y- coordinate, although x- ordinate is constant on line 4y = -16 and y-ordinate is constant on line 3x = 27.
