Answer 5

start with
y = x – 4

for each (x,y) pair of numbers, test if when you "put in" the x number, you "get out" the y number.
For example , for the first pair in Choice A:
(-3, -7)
the first number, -3, is the "x value"
in your equation, replace the "x" with -3, like this
y = -3 - 4
now simplify to get y= -7
notice -7 matches the second number in (-3,-7). that means that pair "works"
check the other two pairs.
can you do that ?
