Question

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

Answer 1

Solve for y. The slope is the number that multiplies x.

Answer 2

Slope-intercept form is as follows:
\(y=\color{red}{m}x+\color{blue}{b}\)
\(~~-m(\text{in} ~\color{red}{\text{red}}) \text{is your slope}\)
\(~~-b(\text{in} ~\color{blue}{\text{blue}}) \text{is your y-intercept}\)

You have:
\(6x+y=12\)
You need to get it into the form above.
