Question

What is the y-intercept of the line 3x – 7y = 42?

Answer 1

Answer:

(0, -6)

Step-by-step explanation:

Slope-Intercept Form: y = mx + b

m - slope

b - y-intercept

Step 1: Write standard form

3x - 7y = 42

Step 2: Rewrite in slope-intercept form

1. Subtract 3x on both sides: -7y = 42 - 3x
2. Divide both sides by -7: y = -6 + 3/7x
3. Rewrite: y = 3/7x - 6

Step 3: Find y-intercept

b = -6
