Identify Slope and Y-Intercept from Graphs

Front

What is the definition of slope?

Back

Slope is a measure of the steepness or incline of a line, calculated as the ratio of the vertical change to the horizontal change between two points on the line.

Front

What are the types of slope?

Back

1. Positive Slope: Line rises from left to right. 2. Negative Slope: Line falls from left to right. 3. Zero Slope: Horizontal line, no rise. 4. Undefined Slope: Vertical line, no run.

Front

How do you identify a positive slope on a graph?

Back

A positive slope is identified when the line rises as it moves from left to right.

Front

How do you identify a negative slope on a graph?

Back

A negative slope is identified when the line falls as it moves from left to right.

Front

What is the y-intercept of a graph?

Back

The y-intercept is the point where the line crosses the y-axis, represented as (0, y).

Front

How can you find the y-intercept from a graph?

Back

To find the y-intercept, look for the point where the line intersects the y-axis.

Front

What does the point (0, 4) represent on a graph?

Back

The point (0, 4) represents a y-intercept of 4, meaning the line crosses the y-axis at y = 4.

Front

What does the point (0, -2) represent on a graph?

Back

The point (0, -2) represents a y-intercept of -2, meaning the line crosses the y-axis at y = -2.

Front

If a line has a slope of 0, what does it look like?

Back

A line with a slope of 0 is horizontal, indicating no vertical change as you move along the line.

Front

If a line has an undefined slope, what does it look like?

Back

A line with an undefined slope is vertical, indicating no horizontal change as you move along the line.
