What is the y-intercept of a line?

Back

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

What does 'm' represent in the equation y=mx+b?

Back

'm' represents the slope of the line, indicating the steepness and direction of the line.

How do you find the slope of a line given two points (x1, y1) and (x2, y2)?

Back

The slope (m) is calculated using the formula m = (y2 - y1) / (x2 - x1).

How can you determine if a line is increasing or decreasing from its slope?

Back

If the slope (m) is positive, the line is increasing. If the slope is negative, the line is decreasing.

How do you convert the standard form of a linear equation Ax + By = C to slope-intercept form?

Back

To convert, solve for y: y = (-A/B)x + (C/B).
