# Increasing, Decreasing, Undefined, or Constant?

Lines can be represented in tables, graphs, and equations.  Identify whether each linear representation below has a slope that is increasing, decreasing, undefined, or constant.

All graphs and tables created in Desmos.com.

 1. Decreasing The $$y$$-values decrease as the $$x$$-values increase. 2. Increasing  The $$y$$-values increase as the $$x$$-values increase. 3.  $$y=\dfrac{1}{3}x-4$$ Increasing The slope is positive. 4.   Decreasing Order the $$x$$-values from least to greatest to show that the $$y$$-values decrease. 5. Undefined The $$y$$-values vary as the $$x$$-values remain constant. 6.  $$y=-3x+2$$ Decreasing The slope is negative. 7.   Constant The $$y$$-values are constant as the $$x$$-values increase. 8.   Decreasing The $$y$$-values decrease as the $$x$$-values increase.
