| Summary: | This lesson studies linear relations (straight lines). It begins with graphing and then moves on to finding x and y intercepts. The main focus of this lesson is writing equations for lines using the slope of the line and a point on the line.
After this lesson, you will be able to:
- draw the graph of a linear relation using a table of values.
- find the x and y intercepts of a linear relation.
- draw the graph of a linear relation using the x and y intercepts.
- draw the graph of a linear relation using the slope and one point.
- write the equation of a line, given the slope and the y intercept using y = mx + b .
- write the equation of a line, given the slope and any point on the line using the slope point formula
y - y1 = m(x - x1).
- use your graphing calculator.
- understand graphs of horizontal, vertical and oblique lines
