Final answer:
The line through the points (5, 2) and (7, 2) is horizontal because the y-coordinate remains constant while the x-coordinates change. Therefore, the line has a slope of 0 and is represented by the equation y = 2.
Step-by-step explanation:
To determine if a line passing through two given points is vertical, horizontal, or neither, we need to compare the x-coordinates and y-coordinates of the given points. The two points given are (5, 2) and (7, 2).
We observe that the y-coordinate is the same in both points (2), but the x-coordinate changes from 5 to 7. This means that the line is horizontal because there is no change in the y-coordinates as we move from one point to the other on the line.
Since horizontal lines have a slope of 0 and do not rise or fall as they move from left to right, we can conclude that:
The line passing through the points (5, 2) and (7, 2) is horizontal.
This line would be represented by the equation y = 2.
It is not vertical or slanted, so it has neither a positive nor a negative slope.
