Question

Which is the slope of the line with equation 6x + y = 12?

Answer 1

6x + y = 12

Convert to slope intercept form(y = mx + b).

Subtract 6x to both sides:

y = -6x + 12

Now it's in slope intercept form(y = mx + b), where 'm' is the slope.

So the slope here is -6.

Answer 2

`The\ slope-intercept\ formula:y=mx+b\ (m-the\ slope)\\-------------------------------\\\\6x+y=12\ \ \ \ |subtract\ 6x\ from\ both\ sides\\y=-6x+12\\\\Answer:\boxed{m=-6}`
