Notes
Enter the equation y = - x for Y2.
View both graphs.
Notice how Y2 decreases
(going down from left to
right) instead of increasing
(going up from left to right).
Negative slopes (m<0) make
the line decrease or go
down from left to right.
Adding 2 will shift the y = x
graph upwards.
View both graphs.
Enter the equation y = x + 2 for
Y2.
