Answer:
The Answer is choice B, (-1,3)
Step-by-step explanation:
The solution to systems of linear equations is the point of intersection of the two lines. In this graph, the two lines cross where the x coordinate is -1 and the y-coordinate is 3
I hope this helps you
20-3n=20-3n
-3n+3n=20-20
0=0
Simply find the difference between the intercept and axis of symmetry then apply it to the other side
-1 › 3 = 4
so
3 + 4 = 7
