What is the y-intercept in the slope-intercept form of a linear equation?

Back

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

Front

If the slope of a line is 1/2, what does this indicate about the line's steepness?

Back

The line rises 1 unit for every 2 units it runs, indicating a gentle slope.

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

Back

Slope (m) = (y2 - y1) / (x2 - x1).
