Remember what we did last year??? Graphing: y = mx + b Writing equations: y = mx + b Lines of Best Fit: on paper and on calculator.

Graphing Equations y = 3x + 2 y = − 4 5 x + 5 –3x + 2y = 12

Writing Equations Slope is 4 and y-intercept is –2. y = 4x – 2 Slope is –3 and point (5, –9) y = -3x +6 Points: (3, –2),(5,4) y = 3x – 11

Lines of Best Fit Find the equation of the best fit for the data in the table. Use your calculator to find the exact equation of the line of best fit. y = 1.05x – 4.66 Temperature 35 30 25 20 15 10 Wind Chill 32 27 22 16 11 6
