Let’s Review • Commutative Property • Classify Numbers • Multi-Step Equations • Absolute Value • Proportions/Percent of increase/decrease • Inequalities : When to switch sign? • ONE DIMENSION • B.A.G.
“I can…” • …locate and graph points on the coordinate plane and identify the components of a coordinate plane • M(F&A)-10-2 • M(G&M)10-9
Rene Descartes • French mathematician and philosopher • Born 1596 • Law degree in 1616, served in the military for 9 years • Set the stage for ‘Analytic Geometry’ • Also introduced exponents
The Coordinate Plane • To locate a point on a coordinate plane, we use ORDERED PAIRS • The first entry is the X-Coordinate • The second entry is the y-Coordinate
Coordinate Plane • Graph a point- means to draw a dot at the point on the coordinate plane that corresponds to the ordered pair • The coordinate plane is divided into four quadrants
Relations- Think of Languages • A Relation is a set of ordered pairs, a table, a graph, or a mapping • Relations can be represented the following ways…
Relations- Think of Languages • Domain- the x-value of a relation • Range- the y-value of a relation
Example • Create a mapping diagram, table, and a graph of the following data; • (-1,7) (3,1) (-8,-5) (6,13) (7,7) (-8,2)
Inverse • The ‘inverse’ is obtained by switching the x-value and the y-value • Example • (5, -1) (7,2) (-3, -5) (4,8)
