NEED HELP ASAP!!!! WILL GIVE BRAINLIEST!!!!

The graph shows two lines, A and B, that Harry graphed.
Part A: How many solutions to the pair of equations for lines A and B does Harry find? Explain how he knows this.
Part B: Write the solution to Harry's equations of line A and B in (x, y) format? Explain to Harry how you know this is the solution for both equations. This is NOT the same as the explanation in Part A.

Answer:

We see two intersecting lines.

It means there is one solution, it is the intersection point.

Solution is (3, 4)

It was easy to find the solution as both lines and their intersection is visible on the graph.

With two parallel lines we would have no solutions and with overlapping lines we would have infinitely many solutions.

If you only have the equations of the lines you need to compare the slopes, if they are different it means lines are intersecting at one point hence one solution.

With same slopes and different y-intercepts there is no solution.

With same slopes and y-intercepts there is infinitely many solutions.
