Step 1: The given equation of the line is

=> 3x + 9y – 18 = 0

Step 2: To find the slope and y intercept, we can write this equation into the form

=> y = mx + b

Step 3: Shift the constant term and x term to the right of the equality

=> 9y = - 3x + 18

Step 4: Now divide the equation by 9 on both sides, then we get

=> y = (

3

Example 2: Find the slope and y intercept of the line 3x + 8y – 15 = 0.

Step 1: the given equation of the line is

=> 3x + 7y – 15 = 0

Step 2: To find the slope and y intercept, we can write this equation into the form

=> y = mx + b

Step 3: shift the constant term and x term to the right of the equality

=> 7y = - 3x + 15

Step 4: Now divide the equation by 7 on both sides, then we get

-> Y= (
