- Integers contains the positive numbers (+), negative numbers (-) and zero.
- The numbers greater than zero are Positive Integers.
- The numbers less than zero are Negative integers.
- An integer and its opposite have the same distance from zero, but they are located on opposite sides of the number line.
In this case we know that
is a Positive Integer, therefore, based on the information mentioned before, we can say that its negative (or its opposite) is:

Answer:
y=-4x+3
Step-by-step explanation:
as x=0
put in y= -4x+3
y= -4(0)+3
y=3
now put x=1 in y= -4x+3
y= -4(1)+3
y= -1
now put x=2 in y= -4x+3
y= -4(2)+3
y=-5
