Slope-Intercept Form: This is another way to write the equation of a straight line, but it uses the slope and y-intercept instead. It is written as y = mx + b, where m represents the slope and b represents the y-intercept.
Standard Form: The standard form of an equation for a straight line is Ax + By = C, where A, B, and C are constants. This form allows for easy comparison between coefficients.
Parallel Lines: Parallel lines have equal slopes but different y-intercepts. They never intersect no matter how far they extend in either direction.
