Question

3 multiple choice 2 points which is an equation of line l? x = 8 x = 2 y = 2 y = -2

Explanation:

Step1: Recall the equation of horizontal and vertical lines

The equation of a horizontal line is \(y = k\) (where \(k\) is a constant, and for all points on the line, the \(y -\)coordinate is \(k\)). The equation of a vertical line is \(x=h\) (where \(h\) is a constant, and for all points on the line, the \(x -\)coordinate is \(h\)).

Step2: Analyze the line \(l\)

Line \(l\) is a horizontal line. We can find a point on the line \(l\). For example, when \(x = 0\), \(y = 2\). Since it is a horizontal line, the equation of the line is of the form \(y=k\). Here \(k = 2\) (because the \(y -\)value is \(2\) for all \(x\) values on the line).

Answer:

\(y = 2\) (the third option)
