Dec 13 - Algebra 1 Find Slope and Identify Y-Intercept review

Front

What is the definition of slope?

Back

Slope is a measure of the steepness 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 or fall. 4. Undefined Slope: Vertical line, no horizontal change.

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 does a slope of zero indicate?

Back

A slope of zero indicates a horizontal line, meaning there is no vertical change as you move along the line.

Front

What does an undefined slope indicate?

Back

An undefined slope indicates a vertical line, meaning there is no horizontal change as you move along the line.

Front

What is the y-intercept?

Back

The y-intercept is the point where a line crosses the y-axis, represented as (0, b) in the equation y = mx + b.

Front

How do you find the y-intercept from an equation?

Back

To find the y-intercept, set x = 0 in the equation and solve for y.

Front

What is slope-intercept form?

Back

Slope-intercept form is a way of writing the equation of a line as y = mx + b, where m is the slope and b is the y-intercept.

Front

Convert the equation -4x - 2y = 6 to slope-intercept form.

Back

The slope-intercept form is y = -2x - 3.
