"Write an equation for a line given two points on the line, one point and the slope of the line, or one point and a parallel or perpendicular line."
"A linear equation in two variables can be used to represent a constraint or condition on two variable quantities in situations where neither of the variables is regarded as an input or an output. A linear equation can also be used to represent a straight line in the coordinate plane."

What you'll learn
- Identify parallel lines as lines with equal slopes
- Identify perpendicular lines as lines whose slopes are negative reciprocals of each other
- Classify a pair of lines as parallel, perpendicular, or neither given their equations
- Write the equation of a line parallel to a given line and passing through a specified point
- Write the equation of a line perpendicular to a given line and passing through a specified point
