Where did the other points come from

the problem is

{x+y=8

x-y=4}

i have the point (6,2) but the graph shows two other which I’m not show how to get

thanks

Step 1

It is observed that from the given graph, the ordered pairs are (0,8), (6,2) and (8,2).

*Known conditions:*

If the lines do not intersect, no solution exist.

If the lines intersecting at one point, unique solution exist.

If the lines are coinciding, infinite number of solutions exist.

The given graph of the lines intersecting at the ordered pair (6,2). Therefore, the solution is unique solution.

Step 2

The points (8,0) and (0, 8) are *x-*intercept and *y*-intercept of the line *x + y = *8 that are not the solution of the system of equations. Also, these points not satisfied both the equations.

Step 3

Substitute *x = *6 and *y = *2 in both the equations to check the ordered...
