Help me please I don’t know what to do

A solution to a system

Is the point two lines cross each other.

3. The lines cross at y = 0 and x = 2, so the solution is x = 2

4. The lines do not cross so there are no solutions.

5. It looks like there is one line which means the two lines are identical so there are infinite solutions

Step-by-step explanation:

3)  y = x - 2

y = -x +2

Both lines are intersecting at (2 , 0).So, (2, 0) is the solution of the equations.

(2,0)

4) Both lines are parallel to each other and they will never intersect. So, it has no solution.

5) Both lines are coincide. So all points in the line are solutions of the equations.

Infinity solutions
