Graphing Equations Flashcard

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

To convert to slope-intercept form (y = mx + b), solve for y in terms of x.

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

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

The equation of a vertical line is in the form x = a, where a is a constant.

The equation of a horizontal line is in the form y = b, where b is a constant.

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

Two lines are parallel if they have the same slope and will never intersect.

Two lines are perpendicular if the product of their slopes is -1.

To graph a linear equation, find the y-intercept, use the slope to find another point, and draw the line.
