Question
Answer the following question:
Reduce the equation 6x + 3y + 8 = 0 into slope-intercept form. Hence find its slope
Solution
Given equation is 6x + 3y + 8 = 0, which can be written as
3y = – 6x – 8
∴ y = `(-6x)/3 - 8/3`
∴ y = `-2x - 8/3`
This is of the form y = mx + c with m = – 2
∴ y = `-2x - 8/3` is in slope-intercept form with slope = – 2
