Answer:
Ques 1)
The type of equation is:
equivalent.
Ques 2)
The solution set below is:
{Infinite set of points on the line}
Explanation:
From the graph that is provided to us we see that the lines a and b overlap that is the two lines intersect each other at infinite number of points.
This means that the lines are equivalent.
Also, the following system is consistent as the solution exist and the solution set is the infinite number of points that lie on the line.
