Question

1. in the equation $5x - 3y = 15$, what is the coefficient of $y$?

a. $15$

b. $-3$

c. $5x$

d. $y$

Explanation:

Step1: Recall coefficient definition

A coefficient is the numerical factor of a term with a variable.

Step2: Identify the term with \( y \)

In the equation \( 5x - 3y = 15 \), the term with \( y \) is \( -3y \).

Step3: Determine the coefficient

The numerical factor of \( -3y \) is \( -3 \), so the coefficient of \( y \) is \( -3 \).

Answer:

b. \(-3\)
