1. Quick Graphs of Linear Equations
Notes 2.4 (Day 1)
Quick Graphs of Linear Equations

2. Slope: m

3. Intercepts y intercept (b) The y intercept will be represented as b.
the point(s) at which the relation crosses the y axis

4. Find the slope and the y intercept.

5. Slope-Intercept Form
y = mx + b
What is the slope and y intercept?

6. Using Slope-Intercept Form to Graph an Equation
Step 1: Write the equation in slope-intercept form by solving for y.
Step 2: Identify the y-intercept b and use it to plot the point (0, b)
Step 3: Identify the slope m and use it to plot a second point on the line. (REMEMBER, )
Step 4: Draw a line through the two points.
Step 5: Make sure your line is continuous.

7. Write a linear equation and graph the line.
m = 3, b = -2

8. Write a linear equation and graph the line.
m = -1, b = 3

9. Write a linear equation and graph the line.
m = -2, b = -1

10. Write a linear equation and graph the line.
