Transcript

• 1. Graphing Linear Equations
• 2. Linear Equation An equation for which the graph is a line
• 3. X-intercept Where the line crosses the x-axis
• 4. X-intercept The x-intercept has a y coordinate of ZERO
• 5. X-intercept To find the x- intercept, plug in ZERO for y and solve
• 6. Slope Describes the steepness of a line
• 7. Slope Equal to: Rise Run
• 8. Rise The change vertically, the change in y
• 9. Run The change horizontally or the change in x
• 10. Finding Slope Step 1: Find 2 points on a line (2, 3) (5, 4) (x1, y1) (x2, y2)
• 11. Finding Slope Step 2: Find the RISE between these 2 points Y2 - Y1 = 4 - 3 = 1
• 12. Finding Slope Step 3: Find the RUN between these 2 points X2 - X1 = 5 - 2 = 3
• 13. Finding Slope Step 4: Write the RISE over RUN as a ratio Y2 - Y1 = 1 X2 - X1 3
• 14. Y-intercept Where the line crosses the y-axis
• 15. Y-intercept The y-intercept has an x-coordinate of ZERO
• 16. Y-intercept To find the y- intercept, plug in ZERO for x and solve
• 17. Slope-Intercept y = mx + b m = slope b = y-intercept
• 18. Step 1: Mark a point on the y-intercept
• 19. Step 2: Define slope as a fraction...
• 20. Step 3: Numerator is the vertical change (RISE)
• 21. Step 4: Denominator is the horizontal change (RUN)
• 22. Step 5: Graph at least 3 points and connect the dots
