Answer
A
negative 1 point 6 comma 1 point 6
B
1 point 5 comma negative 1 point 5
C
1 point 6 comma negative 1 point 6
D
negative 1 point 5 comma 1 point 5

Explanation

Since both expressions equal y, set them equal: 1.5x − 4 = −x. Adding x and 4 gives 2.5x = 4, so x = 1.6. Substitute into y = −x to get y = −1.6. The solution is (1.6, −1.6), choice D.
