Answer:
Equation of line A: x = 6
Equation of line B: y = 4
Equation of line C: x = -1
Equation of line D: y = -2
Explanation:
1) Line A is a vertical line that passes through the point x = 6 on the graph.
Thus;
equation of line A is x = 6
2) Line B is a horizontal line that passes the point y = 4 on the graph.
Thus;
Equation of line B is y = 4
3) Line C is a vertical line that crosses the point x = -1 on the graph.
Thus;
Equation of line C is x = - 1
4) Line D is a horizontal line that passes the point y = -2 on the graph.
Thus;
equation of line D is y = -2
