Answer 1

A) -3/2

Explanation:

Slope-Intercept Form: y = mx + b

m - slope

b - y-intercept

Step 1: Write equation

12x + 8y = -6

Step 2: Write in slope-intercept form

1. Subtract 12x on both sides: 8y = -12x - 6
2. Divide both sides by 8: y = -3/2x - 3/4

Step 3: Find slope

Slope of a parallel line always has the same slope of the original line.

m = -3/2 (Original)

m = -3/2 (Parallel)
