It’s a because Josh and him had 8907
No no no no no no no no no
You put the values of x into the equation to work out y, so the y column would be -5, -1, 3, 7 (for question 6)
For question 7, the y column would be 2,2,0,-2
Use these values to draw the graphs :)

Step-by-step explanation:
Answer:
B. 1,4
Step-by-step explanation:
1. substitute 4x for y in the second equation since we know y=4x(to find x)
6x-4(4x)=-10
2.solve for x
6x-4(4x)=-10
-4•4x=-16x
6x-16x=-10
6x-16x=-10x
-10x=-10
-10x/-10=-10/-10
x=1
3.substitute 1 for x in either equation(since x=1)to find y
y=4(1)
y=4
x,y=1,4
hope this helps!
