Explanation:
I will start from X=-1
A
1: If the equation is Y=2x-5
you will have to substitute x with -1 since X=-1
After it will become y=-2-5, which will become y=-7
2: x=0 so u substitute x with 0, so it will become Y=0-5 which become y=-5
3: X=1 so u substitute x with 1, so it will become y=2-5 which become Y=-3
4: X=2 so u substitute x with 2, so it will become y=4-5 which become Y=-1
B I am confused Abt Q3 does it mean question 3 or no
C: I can't really answer it since I don't know what u mean at B
