To change a line from solid to dotted, you would typically do this to represent that the line does not include points on it (for example, in inequalities).
For the options given:
A) x = 1 – This is a vertical line.
B) y = 2 – This is a horizontal line.
C) y = x – This is a diagonal line with a slope of 1.
D) y = -x – This is a diagonal line with a slope of -1.
To represent inequalities, for instance, you might use dotted lines when shading regions based on these lines. For example, if you want to shade above or below the line, you have to determine if certain equations represent a strict inequality (using dotted) or a non-strict inequality (using solid).
For a correct answer, you might choose C) y = x as a choice for a dotted line because it’s often used in inequalities and further examination of regions can be performed if needed.
If you have a specific inequality or context, that could help in making a definitive choice!
