Substitute each value in for y, and check if there is an x value that could lead to the y value. For example, checking the first choice.
−1.9=x−1x
−1.9x+1.9=x
1.9=2.9x
x=2.91.9
Which is not possible since x>1.
Note that if x>1, the fraction will always be a positive number over another positive number.
x−1x>0 if x>1
Next, note that the numerator will always be larger than the denominator, which means that the quotient will be greater than 1.
