On the number line, the number \\(y\\) is \\(3.25\\) units to the right of \\(-2\\). What is the value of \\(y\\)?
Answer and explanation
Correct answer: \\(1.25\\)
Moving to the right on a number line means adding the given distance to the starting number. Thus, \\(y=-2+3.25=1.25\\). Option D results from subtracting the distance, which would represent moving to the left. Exam tip: add for a rightward move and subtract for a leftward move.
