Question

what have you learned so far?
write a quick summary (2-3 sentences) describing what
youve learned so far about describing horizontal lines

Explanation:

Horizontal lines on a coordinate plane have a constant y-value for every x-value, meaning their slope is always 0. The standard equation for a horizontal line is written as $y = k$, where $k$ is the fixed y-coordinate that the line passes through, such as $y = 4$ for a line sitting 4 units above the x-axis. These lines are perpendicular to vertical lines, and they never rise or fall as you move along the x-axis.

Answer:

Horizontal lines are defined by a constant y-value across all x-values, so they have a slope of 0. Their standard equation is $y = k$, where $k$ is the fixed y-coordinate the line intersects. Unlike slanted lines, horizontal lines neither rise nor fall as you traverse the x-axis.
