This week we learned about slopes and graphs, and when interpreting the graph it is hard to understand what the graph is reading. Specifically knowing if the graph is showing a positive(+), negative(-), a zero slope, or a undefined slope.

POSITIVE slope

The slope starts at the left and increases to the right

NEGATIVE slope

The slope starts at the left and decreases to the right

ZERO slope

The slope has to go in a perfectly horizontal line into the quadrant horizontal to the other.

UNDEFINED slope

The slope has to go in a perfectly vertical into the quadrant directly below or above.
