Algebra 1Ch.6 Notes Page 47P47 6-7 Scatter Plots and Equations of Lines
Finding Equations from two points.
(3, 2) and (5, 8)
(-4, 6) and (-2, 8)
Calculate Slope (m) - Calculate Y-Intercept (b)
y = mx + b
Writing Equations of Trend Lines
Two Points on the Trend Line are (14, 30) and (24, 48)
Predict the wingspan of a hawk that is 28in long.
Use data points to make a Scatter PlotDraw in a Trend Line
Use the two points to write the equation of the line.
Graph the data below. Draw the trend line.Write the equation of the Trend Line.Estimate the number of Calories if a food has 14g of fat.
