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. YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY Your solution: The coordinates of x=x1 point is (x1, 1.1 x1 + .8). The coordinates of x=x2 point is (x2, 1.1 x2+ .8). Using the formula (y2 –y1)/(x1-x2) we can find our slope. The rise would be (1.1 x2+ .8)- (1.1 x1 + .8) = 1.1 x2 + .8 – 1.1 x1 - .8 we can eliminate the positive .8 and negative .8 to leave us with 1.1 x2 -1.1 x1. The run would be x2-x1. The slope is (1.1 x2-1.1x1)/(x2-x1) = 1.1 (x2-x1)/(x2-x1) are (x2-x1) can be eliminated to leave us with the slope 1.1 confidence rating #$&*5 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Given Solution: 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. &&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&& Self-critique (if necessary): ------------------------------------------------ Self-critique rating #$&* ********************************************* Question: `q002. For the function y = 3.4 x + 7, what are the coordinates of the x = x1 point, in terms of the symbol x1? What are the coordinates of the x = x2 point, in terms of the symbol x2? What therefore is the rise between these two points, and what is the run? What is the average slope of the graph between these two points? Be sure to simplify your result. YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY Your solution: The coordinates of the x = x1 point are ( x1, 3.4 x1 + 7) . The coordinates of the x = x2 point are ( x2, 3.4 x2 + 7). Using the formula (y2 –y1)/(x1-x2) we can find our slope. The rise would be (3.4 x2 + 7) - (3.4 x1 + 7) = 3.4 x2 + 7 - 3.4 x1 - 7 we can eliminate the positive 7 and negative 7 to leave us with 3.4 x2 - 3.4 x1 . The run would be x2-x1. The slope is (3.4 x2 - 3.4 x1) / (x2 - x1) = 3.4 (x2 - x1) / (x2 - x1) the ( x2-x1) can be eliminated to leave us with the slope 3.4 confidence rating #$&*5 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

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. "
