Distance and Midpoint Sections 1.3

Distance On a coordinate plane Finding the length of a line segment. On a number line On a coordinate plane

Distance On a number line formula: d = | x2 – x1 | On a coordinate plane formula:

Midpoint On a coordinate plane Finding the location of the midpoint of a line segment. On a number line On a coordinate plane Remember… A midpoint is a location of the midpoint.

Slope and Linear Equations Sections 3.3-3.4

Slope Slope is the steepness of a line. It is represented by rise over run. Formula -

Special Slopes Horizontal lines Slope = zero Vertical lines Slope = undefined Parallel lines Slopes are the same. Intersecting lines Slopes are different and not perpendicular. Perpendicular lines Slopes are the negative reciprocal of each other.

y = mx + b Slope-intercept Form y-intercept Plot a point on the y-axis using the y-intercept value.

Application Parallelograms Trapezoids Circles Finding endpoint of a segment Graphing linear equations Parallel & perpendicular slopes/lines x and y-intercept
