Space

Answer:

C. -3/5

General Formulas and Concepts:

Algebra I

Slope-Intercept Form: y = mx + b

m - slope

b - y-intercept

Step-by-step explanation:

Step 1: Define

3x + 5y + 15 = 0

Step 2: Rewrite

  1. Subtract 15 on both sides:                    3x + 5y = -15
  2. Subtract 3x on both sides:                    5y = -3x - 15
  3. Divide 5 on both sides:                         y = -3/5x - 3

Step 3: Identify

Break up the function

Slope m = -3/5

y-intercept b = -3
