Question

slope is the of a line. it is also known as the rate of change. if a line is slanting upwards we say it has a slope. if a line is slanting downwards we say it has a slope. a slope of zero means the line is. an undefined slope means the line is. all straight line graphs are known as relationships. to find the slope of a line we use the formula over.

Explanation:

Slope measures how steep a line is. An upward - slanting line has a positive slope, a downward - slanting line has a negative slope. A zero - slope line is horizontal, an undefined - slope line is vertical. The formula for slope is rise over run, and straight - line graphs are linear relationships.

Answer:

1. steepness
2. constant
3. positive
4. negative
5. horizontal
6. vertical
7. linear
8. rise
9. run
