Question

give the equation of the line illustrated.
○ x = 1
○ x = -1
○ y = -1
○ y = 1

Explanation:

Step1: Identify line - horizontal or vertical

The line is horizontal as it is parallel to the x - axis.

Step2: Determine y - value

For a horizontal line, the y - coordinate is constant for all x - values. Looking at the graph, the line passes through the point where y = 2 (assuming the grid lines are of unit length and the line is at y = 2 visually). But among the options, the correct form for a horizontal line is chosen based on the general form of a horizontal line equation y = c (where c is a constant).

Answer:

If we assume the line is at y = 1 (since it seems to be at y = 1 from the options), the correct answer is D. y = 1
