Lesson 12 Practice Problems 1. Select all of the ordered pairs (x, y) that are solutions to the linear equation 2x+3y= 6. A. (0, 2) B. (0,6) C. (2,3) D. (3,-2) E. (3,0) F. (6,-2) 2. The graph shows a linear relationship between x and y. x represents the number of comic books Priya buys at the store, all at the same price, and y represents the amount of money (in dollars) Priya has after buying the comic books. y (dollars) Grade 8 Unit 3 Lesson 12 20 15 10 5 1 2 i Mathematics 3 x (comics) a.

What is true about the point (2, y)? O If y = - 4, then the point is in quadrant I. O If y = -3, then the point is in quadrant IV. O.If y = 3, then the point is in quadrant II. O If y = 2, then the point is in quadrant II.

If aN O for a moving object, then the object is moving in a straight line. %3D O True O False

The point with coordinates (5, 4.9) is on the graph. Write a sentence that explains the meaning of this ordered pair. The proton travels ft in nanoseconds.

Do you know that? Given the points on a line, the line can be divided into parts which we call subsets of a line. Ray Segment Ray Overview R figure 1 Line segment A line segment is part of a line that has two endpoints. Line segment RO or OR, line segment RB or BR, line segment RI or IR, line segment OB or BO, line segment Ol or 10 and line segment BI or IB are line segments in the given figure above. In notation, we write RO or OR, RB or BR, RIor IR, OB or B0, OTor lo and BTor TB. Ray figure 2 A ray is also a part of a line but has only one endpoint, and extends endlessly in one direction. We name a ray by its endpoint and one of its points. (See igure 2) From the figure we define it as ray RF and we can also name it as ray LF. In nota- tion, we write RF anc LER. It is not correct to name it as ray FR or ray LR because we always sta. un na.ng it at the endpoint. Activity (PERFORMANCE TASK 1) Illustrate the statement below and answer the following questions. Line b consists of the…
