Answer:y= -4
Step-by-step explanation:
change the x to (3)
y=-4(3)+8
Then do -4 x 3=12
y=-12+8
If the negative number is higher then the positive number it will remain negative. Example it like you owe someone £12 and you gave them back £8. So you still owe them 4 pound.
so the answer to your question is y=-4
