Question

okay

Answer 1

try putting y=0 in both the equations...then find corresponding value of x
similarly put x =0 and find value of y.
Locate these points in the graph you will get your answer

Answer 2

A) 2x + y = –1
B) 3x + 2y = –6
Multiplying equation A by -2
-4x -2y = 2
adding this to equation B
3x + 2y = –6
-x = -4
x = 4

Inputting this to equation A)
8 +y =-1
y=-9

You now have the equations solved and looking at the graphs, can you see which one has x = 4 and y = -9 ?

Answer 3

No - once you cancel out the y, then you have a value of x which you then input into the first equation. x = 4
2x + y =-1
8 + y = -1
y = -9

Answer 4

Yes if you notice in the second graph, the 2 lines intersect when x=4 and y=-9

Answer 5

all right !!!!!!!!!!!!!!

Answer 6

thanks for the medal :-)
