|
Run |
How much you move horizontally while calculating the slope of a line.
|
|
|
Rise
|
How much you move vertically while calculating the slope of a line.
|
|
|
Slope
|
The way you calculate points on a line. The slope is the angle of the line compared to the axis.
|
|
|
Opposite Reciprocals
|
The result of flipping the numerator and denominator of a fraction and the sign.
|
|
|
Positive Slope
|
If a slope is positive it moves from the bottom left quadrant to the top right one.
|
|
|
Negative Slope
|
If a slope is negative it moves from the top left quadrant to the bottom right one.
|
|
|
Zero Slope
|
If a line has a slope of zero than it runs horizontally across the graph. It can be remembered through the line representing the top of a Z.
|
|
|
Undefined
|
(No Slope)
If a line has no slope, or if it's slope is undefined then it forms a straight vertical line, which looks like the leftmost line of an N. |
|
|
Point-Slope Form
|
y – y1 = m(x – x1)
|
|
|
Slope-Intercept Form
|
y = mx + b
(Standard Form) |
|
|
Parallel Lines
|
Equidistant lines that never intercept.
|
|
|
Intersecting Lines
|
Lines that intersect at a point.
|
|
|
Intersecting Lines
|
Lines that intersect at a point.
|
|
|
Coinciding Lines
|
Lines that have the same slope and y-intercept.
|
|
|
Perpendicular Lines
|
Lines that form a perfect right angle when they intersect.
|
|
|
Skew Lines
|
Lines that don't intersect and aren't parallel.
|
|
|
Parallel Planes
|
Planes that do not intersect.
|
|
|
Transversal
|
A transversal is a line that passes through two lines in the same plane at two distinct points.
|
|
|
Perpendicular Bisector
|
A line that always bisects an angle no matter the slope.
|
|
|
Perpendicular Distance
|
It is the length of the line segment which joins the point to the line and is perpendicular to the line.
