Graphing Lines Review

Front

What is the y-intercept?

Back

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

Front

Which of these represents slope-intercept form?

Back

y = mx + b, where m is the slope and b is the y-intercept.

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

Back

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

What is the formula for the equation of a line in point-slope form?

Back

y - y1 = m(x - x1), where m is the slope and (x1, y1) is a point on the line.
