Question

Determine the slope and equation of a line passing through the point (2, –1) and parallel to the x-axis

Answer 1

slope = 0

eq of line: y = -1

Explanation:

A line parallel to the x-axis is a horizontal line. The equation of a horizontal line is " y = anumber". Horizontal lines have 0 slope. The point given is (2,-1). In the point (2,-1) the y is -1. The equation of the horizontal line thru (2,-1) is

y = -1
