Back

The slope is -2.

Front

What is the y-intercept of the line represented by the equation y = -2x + 3?

Back

The y-intercept is 3.

Front

What is the slope of the line represented by the equation y = 4x - 8?

Back

The slope is 4.

Front

What two components are needed to write a linear equation?

Back

You need the rate (slope) and the y-intercept.

Front

What is the y-intercept or starting point for the table if the answer is 2?

Back

The y-intercept is 2.

Front

Define slope in the context of a linear equation.

Back

Slope is the measure of the steepness of a line, represented as 'm' in the equation y = mx + b.

Front

What does the y-intercept represent in a linear equation?

Back

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

Front

If a line has a slope of 0, what does that indicate about the line?

Back

A slope of 0 indicates that the line is horizontal.

Front

If a line has an undefined slope, what does that indicate about the line?

Back

An undefined slope indicates that the line is vertical.

Front

How do you find the slope between two points (x1, y1) and (x2, y2)?

Back

The slope is calculated as (y2 - y1) / (x2 - x1).
