Graphing Lines
We have looked at 2 ways to graph
lines
  1. Table of Values
  2. Intercepts

Today we are going to put slope to
work.
This is called the Slope-Intercept
or Slope Point method.

First thing you need is a point on
the line, either one will be...
Graph y = 4x -2 using the slope intercept
method.

                        slope = 4/1

                        y-intercep...
Graph 3y + 4x + 9 = 0 using the
slope -intercept method.

First step is to convert to the
slope-intercept form y = mx + b
...
y = -4/3x - 3     slope = -4/3
                y intercept = (0,-3)

March 8 Graphing Slope Intercept

  1. 1. Graphing Lines
  2. 2. We have looked at 2 ways to graph lines 1. Table of Values 2. Intercepts Today we are going to put slope to work.
  3. 3. This is called the Slope-Intercept or Slope Point method. First thing you need is a point on the line, either one will be given or use the y-intercept. Then use the slope (rise/run) to find another point.
  4. 4. Graph y = 4x -2 using the slope intercept method. slope = 4/1 y-intercept = (0,-2)
  5. 5. Graph 3y + 4x + 9 = 0 using the slope -intercept method. First step is to convert to the slope-intercept form y = mx + b 3y = -4x - 9 3y = -4x - 9 3 3 3 y = -4/3x - 3
  6. 6. y = -4/3x - 3 slope = -4/3 y intercept = (0,-3)
