Coordinate Geom: Graphing Linear Relations 195

This lesson is part of the series: Coordinate geometry, Pre Calculus

This 79 minute coordinate geometry lesson covers graphing linear relations (straight lines), x & y intercepts and lines perpendicular to a graph of an equation. After this lesson you will be able to:
- find the slope and y intercept from an equation
- write equations of lines given one point and the slope or given two points
- understand relations (sets of ordered pairs)
- graph linear relations using:
a calculator, table of values, x and y intercepts, slope of a line and a point on the line
- understand a missing variable
- work with positive, negative, zero and undefined slope
- understand slope intercept form y = mx + b and understand point slope form
- recognize the standard form of a linear equation

Sample question: Find the equation in standard form of the line passing through (4, -2) and perpendicular to the graph of 5x – y – 1 = 0

This lesson contains explanations of the concepts and 23 example questions with step by step solutions plus 7 interactive review questions with solutions.
