Which system of equations intersect at point A in this graph

second one and last one

Step-by-step explanation:

Hello

The point A is (-2,1)

is it solution of the first system? you need to replace x by -2 and y by 1 and see if there is equality

1 = 10*(-2)-1 is wrong so this is not the first one

1=4*(-2)+9=-8+9=1 is true and

1=-3*(-2)-5=6-5=1 is true so the second system of equations intersects at point A

and the last one is ok as well as

1=-6+7=1

-=2-1=1

hope this helps

i did it myself and i got 4.2 (b) hope its right

ou would have 12 of each
