Final answer:
An equivalent equation to -y>-4 is y<4. To obtain an equivalent equation, we divide both sides of the inequality by -1, which changes the direction of the inequality.
Step-by-step explanation:
An equivalent equation to -y>-4 is y<4.
To obtain an equivalent equation, we divide both sides of the inequality by -1, which changes the direction of the inequality. Therefore, the inequality becomes y<4.
This means that any value of y that is less than 4 will satisfy the original inequality.
