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

Linear Equations in Standard, PointSlope and Slope Intercept Form
Use the sliders to change the yintercept 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 pointslope form.
