1. Algebra 1 Section 4.1 Plot points and scatter plots To locate a point in a plane, you can use an ordered pair in the form (x,y) in a Cartesian Coordinate System. Plot the points. A (3,4) B (-2,5) C (-5,-2) D (3,-4) E (0,2) F(-3,0)

2. Name the quadrant or the axis in which each point is located. (-2,1) (-3,-5) (0,4) (2,-6) The x value of an ordered pair is the independent value and the y value is the dependent value. Many real life situations can be modeled by creating a scatter plot.

3. Predictions can be made by creating a scatter plot. Predict the arm span for heights of 72 in and 55 in. height in inchesArm span in inches 60 57 40 41 52 50 62 63 48 45 58 60 70 68

4. Consider the graph Which variable is the independent? Which variable is the dependent? What is the value of A when w = 4? Estimate the weight when A = 10. Generally, how are weight and age related?
