Look in the graph. The equations are written there.
OpenStudy (jollypikachu300):
2
OpenStudy (mathstudent55):
Correct. There are 2 equations.
Both equations were graphed and they both have exactly the same graph.
They both graph as the same line.
Every point of one equation is also a point of the other equation.

so then a

No. Not exactly one solution.
The entire line is a solution to the system of equations.
How many points are there on a line?

No.
Read what I wrote above.
This system has solutions.
Every point on the line is a solution.
How many points are there on a line?
Also, see my picture above.
Which case do you have of the three graphs I showed above?

Correct.
There is an infinite number of points in a straight line.
The solution of the system of equations is every point on the line, so there are infinitely many solutions.
