Answer 1

1) Slope is the ----- of a line. It is also known as the ------ rate of change.

Slope means steepness and it is a constant rate of change meaning that it does not change.

2) If a line is slanting upwards we say it has a ------ slope.

Slanting upward means a positive slope, for example when you are moving uphill.

If a line is slanting downwards we say it has a ------ slope

Slanting downward means a negative slope, for example when you are moving downhill.

3) A slope of zero means the line is -----

a Slope of 0 means that the line is horizontal. for example when you are moving on a straight road.

4) An undefined slope means the line is -----

An undefined slope means that the line is vertical. for example when you are climbing a vertical wall.

5) All straight line graphs are known as ------ relationships.

They are known as linear relationships.

6) To find the slope of a line we use the formula ----- over ------

We use the slope formula that is rise over run.
