Do now  State each point on the graph.

Do Now  1. The point (-9, 2) is reflected across the x-axis. What are the coordinates of the reflection?  2. What is the distance between the points (8, -4) and (-5, -4)?  3. What is the distance between the points (-7, -5) and (-7, -8)?  4. A truck travels from warehouse A at (-4, 8) to warehouse B at (-4, -1). If each unit represents 20 miles and the truck is traveling 60 miles per hour, how long will it take the truck to travel this distance?

VOCABULARY

Scales  The scale of an axis is the number of units that each grid line represents. So far, the graphs in this lesson have a scale of 1 unit, but graphs frequently use other units.  Scales can also be referred to as miles, yards, feet etc…

Distance in the Coordinate Plane: Reflecting in the Coordinate Plane  A point on a coordinate plane can be reflected across an axis. The reflection is located on the opposite side of the axis, at the same distance from the axis. What is the relationship between the coordinates of a point and coordinates of its reflection across each axis? Across y-axis: opposite x-coordinate and same y- coordinate as the original point; Across x-axis: same x-coordinate and opposite y- coordinate as the original point
