Question

Which statement about the lines below is true?

4y = -16 and 3x = 27
Select all that apply.
A Line 4y = -16 is horizontal.
B. Line 3x = 27 is vertical.
O
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.

Answer 1

All these statements are true. See explanations, below.

Explanation:

A Line 4y = -16 is horizontal. TRUE. Note that y = -4 here.

B. Line 3x = 27 is vertical. TRUE. Note that x = 9, which is a vertical line.

C. For both lines, all points on the line have an x- and a y-coordinate. TRUE. But for 4y = -16, the y-coordinate is always the same: -4; for x = 9, the x-coordinate is always the same.

D. For either line, one of the coordinates of all the points is always the same value. TRUE (See C above)
