What is the y-intercept of a linear equation?

Back

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

Front

What is slope-intercept form?

Back

Slope-intercept form is a way of writing linear equations in the form y = mx + b, where m is the slope and b is the y-intercept.

Front

Convert the equation 2x + 3y = 6 to slope-intercept form.

Back

y = -rac{2}{3}x + 2.

Front

What are the coordinates of the x-intercept?

Back

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

Front

How do you find the slope from an equation in standard form?

Back

To find the slope from an equation in standard form Ax + By = C, rearrange it to slope-intercept form (y = mx + b) to identify m.

Front

What does the slope of a line represent?

Back

The slope represents the rate of change of y with respect to x, indicating how steep the line is.

Front

What is the formula for calculating the slope between two points (x1, y1) and (x2, y2)?

Back

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

Front

What is the significance of a positive slope?

Back

A positive slope indicates that as x increases, y also increases, showing a direct relationship.

Front

What does a negative slope indicate?

Back

A negative slope indicates that as x increases, y decreases, showing an inverse relationship.
