SOL

A.6b - The student will graph linear equations and linear inequalities in two variables, including writing the equation of a line when given the graph of the line, two points on the line, or the slope and a point on the line

## Point-Slope Form

The line below can be manipulated by moving slider 1 and point A

## Linear Equations in Standard, Point-Slope and Slope Intercept Form

Use the sliders to change the y-intercept equation to match the Standard Form equation. Remember, Standard Form is Ax + By = C. Click on a point and use your arrow keys to see the point-slope form.

Homework
Journal
1. Opinion: Should there be a dress code in schools? Why or why not?
2. Slope: Would you want to run up a flight of steps that has a slope of 5? What about steps with a slope of -1/2? Include diagrams in your explanation.
