15:11:42 `questionNumber 90000 `q001. Note that this assignment has 2 questions For the function y = 1.1 x + .8, what are the coordinates of the x = x1 point, in terms of the symbol x1? What are the coordinates of the x = x2 point, in terms of the symbol x2? What therefore is the rise between these two points, and what is the run? What is the average slope of the graph between these two points? Be sure to simplify your result.

RESPONSE --> y = 1.1 x + .8 y = 1.1 (x1) + .8 (x1, 1.1x1+.8) y = 1.1 (x2) + .8 (x2,1.1x2+.8) Rise= 1.1x2+.8-1.1x1+.8 Rise=1.1x2-1.1x1 Run=x2-x1 Slope=1.1x2-1.1x1/x2-x1 Slope=1.1 confidence assessment: 2

15:11:50 `questionNumber 90000 In terms of the symbol x1 the coordinates of the x = x1 point are ( x1, 1.1 x1 + .8) and the coordinates of the x = x2 point are ( x2, 1.1 x2 + .8). The rise between the two points is therefore rise = (1.1 x2 + .8) - (1.1 x1 + .8) = 1.1 x2 + .8 - 1.1 x1 - .8 = 1.1 x2 - 1.1 x1. The run is run = x2 - x1. The slope is therefore (1.1 x2 - 1.1 x1) / (x2 - x1) = 1.1 (x2 - x1) / (x2 - x1) = 1.1.

15:14:52 `questionNumber 90000 `q002. For the function y = 3.4 x + 7, what are the coordinates of the x = x1 point, in terms of the symbol x1? What are the coordinates of the x = x2 point, in terms of the symbol x2? What therefore is the rise between these two points, and what is the run? What is the average slope of the graph between these two points? Be sure to simplify your result.
......!!!!!!!!...................................
RESPONSE --> y = 3.4 x + 7 y = 3.4 (x1)+ 7 (x1, 3.4 x 1+ 7) y = 3.4 (x2) + 7 (x2,3.4 x 2+ 7) Rise= 3.4 (x2) + 7-3.4 (x1)+ 7 Rise=3.4x2-3.4x1 Run=x2-x1 Slope=3.4(x2-x1)/x2-x1 Slope=3.4 confidence assessment: 2

15:15:03 `questionNumber 90000 In terms of the symbol x1 the coordinates of the x = x1 point are ( x1, 3.4 x1 + 7) and the coordinates of the x = x2 point are ( x2, 3.4 x2 + 7). The rise between the two points is therefore rise = (3.4 x2 + 7) - (3.4 x1 + 7) = 3.4 x2 + 7 - 3.4 x1 - 7 = 3.4 x2 - 3.4 x1. The run is run = x2 - x1. The slope is therefore (3.4 x2 - 3.4 x1) / (x2 - x1) = 3.4 (x2 - x1) / (x2 - x1) = 3.4.
