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.

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.

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).
