Question

Answer the following question:

Reduce the equation 6x + 3y + 8 = 0 into slope-intercept form. Hence find its slope

Answer 1

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
