• endpoint

slope of parallel lines

• same slope

• change the sign and take the reciprocal

The slope intercept form

• y = mx + b

• y - y1 = m(x-x1)

• y2 - y1/x2-x1

• Ax + By = C

Which is this formula: y - y1 = m(x-x1)

• slope intercept form

• point slope

• slope of two points

• standard form
