Answer:
<u>System of equations</u>


--- solution
See attachment for graph
Step-by-step explanation:
Solving (a): Linear equations with 1 solution
The only condition to this is that, the system must have 1 solution.
Other than that, there is no other condition.
A linear equation is represented as:

For the equation to have 1 solution;

And example of such equation is:


Solving (b): The graph
See attachment for graph
The solution is the point of intersection of both lines of the graph. So, we have:

Answer: Congruent, or equal
Step-by-step explanation:
Very simple. Since there are parallel lines, the corresponding angles they make with the other line would be the same.
It should be range your welcome
