Right Brain vs. Left Brain Definition This theory of the structure and functions of the mind suggests that the two different sides of the brain control two different “modes” of thinking. It also suggests that each of us prefers one mode over the other. Discussion Experimentation has shown that the two different sides, or hemispheres, of the brain are responsible for different manners of thinking. The following table illustrates the differences between left-brain and right-brain thinking: http://www.funderstanding.com/content/right-brain-vs-left-brain

Find the slope of the line joining the points (2, 4) and (5, 3). Traditional method Forwards method
2) Find the slope of the line joining the points (-5,7) and (-3, -8). 1) Find the slope of the line joining the points (3,8) and (-1,2).
This method is used to find a second point on the line if you know a point and the slope. Find the next point on the line using the slope. y If m = 2 =y rise = 2 = y run = 5 = x From (4, 8) find the next point. 2 5 5 x r I S e run Christine’s Method (x , y) + = 5 (9, 10) (x, y) 2 (4, 8) (x , y) (4, 8) (9 , 10) x
