Question

the number line shows an unknown number, y. is -4y positive or negative? positive negative

Explanation:

Step1: Determine sign of y

From the number - line, y < - 1, so y is negative.

Step2: Analyze - 4y

The number - 4 is negative. When we multiply two negative numbers (negative - 4 and negative y), the result is positive. (-4)×y=(-1)×4×y = (-1)×(4y). Since y is negative, 4y is negative, and (-1)×(4y) is positive.

Answer:

positive
