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.
