Answer:
So you have the multiplication and substitution right. It's just the subtraction.
Step-by-step explanation:
Now, the equation was y = 4x - 2
In the first one x = -3
So it will be 4(-3) - 2
Note: Anytime you see a bracket it means multiplication.
4× -3 = -12 and
-12 - 2 = -14
This is because a negative number minus another number is always negative.
And when dealing with negative numbers you add them but you negate the answer.
For example;
The second one will be -8 - 2
And 8 + 2 = 10
But since the numbers are negative we just negate the 10 making it - 10.
I hope this helps
