Answer:
1. D y = 8
2. C y = −8
Step-by-step explanation:
1.
Both points have y-coordinate 8, so the line is horizontal.
A horizontal line has equation
y = k
where k is the y-coordinate of all of its points.
The y-coordinate of all points on this line is 8.
Answer: y = 8
2.
A line with 0 slope is a horizontal line. All points on a horizontal line have the same y-coordinate.
A horizontal line has equation
y = k
where k is the y-coordinate of all of its points.
The y-coordinate of the given point is -8, so all points must have -8 as the y-coordinate.
Answer: y = -8
