Solving for Slope

The other day we worked on the worksheet, "Solving for Slope". You were given linear equations in Standard Form (Ax + By = C) and asked to convert the equations into Slope-Intercept Form and to determine the slope.

Here is an interactive website that shows you the steps to convert Standard Form linear equations.

Here is a video demonstration by a teacher converting a Standard Form equation.

Here is a video for those that would like to review Slope-Intercept Form.

"Solving for Slope" asked some interesting questions regarding the general equation Ax + By = C

• How could you tell if the line is has a positive or negative slope just by looking at A, B, and C?
• How could you tell if the line has a positive slope and is steeper than y = x just by looking at A, B, and C?
• How could you tell if the line has a negative slope and is steeper than y = -x just by looking at A, B, and C?

And finally, could you convert the other way around -- given an equation in Slope-Intercept Form, convert it into Standard-Form?
