Coordinate Plane. It is made up the X-axis (a horizontal number line) and Y-axis (a vertical number line). The X and Y axes intersect at the origin (0,0) and are perpendicular to each other.
We use ordered pairs of numbers (X, Y) to locate points in the plane. To find a point on the plane, first move horizontally along the x-axis and locate the X value; then move vertically to locate the Y value; draw a point where they meed, as shown.
EQ06 Find the Slope 1
EQ08 Find the Slope 2
EQ07 Slope (given 2 points)
EQ09 Find the slope and the y-intercept
A function represents a dependence of one quantity on another and can be described in a variety of ways. In this unit, in addition to deriving and interpreting y=mx and y=mx + b, students will represent directly proportional and linear relationships using verbal descriptions, tables, graphs, and formulas, and translate among these representations.
Roman numerals were used by the Romans as their numbering system. They are expressed by letters of the alphabet:
|I = 1|
|V = 5|
|X = 10|
|L = 50|
|C = 100|
|D = 500|
|M = 1000|
