Slopes of Lines Flashcards
1
Q
What is Slope?
A
The slope of a line is its steepness.
2
Q
What is Principle 1 of Slopes?
A
As a point moves from left to right along a line that is rising, y increases and x and the slope of the line is positive.
3
Q
What is Principle 2 of Slopes?
A
As a point moves from left to right along a line that is falling, y decreases as x increases and the slope of the line is negative.
4
Q
When does a line have Zero Slope?
A
When the line is parallel to the x-axis because it is horizontal.
5
Q
When does a line have No Slope (Undefined)?
A
When the line is parallel to the y-axis.
6
Q
What is Principle 3 of Slopes?
A
If a line is parallel to the x-axis, its slope is 0.
7
Q
What is Principle 4 of Slopes?
A
If a line is parallel to the y-axis, it has no defined slope.
