Set A, pages 402-404

What ordered pair names Point A? Start at the origin. The x-coordinate is the distance to the right or left along the x-axis. The y-coordinate is the distance up or down along the y-axis. Point A is at (+5, +3).

Remember to name a point on a coordinate grid, first find the x-coordinate. Then find the y-coordinate. Write the coordinates in (x, y) order.
Question 1.
Which point is located at (4, 3)?

Question 2.
Which point is located at (+2, +2)?

Question 3.
Which point is located at (4, +4)?

Question 4.
What ordered pair names Point T?

Question 5.
What ordered pair names Point W?

Question 6.
What is the new ordered pair if Point A is moved to the left 5 spaces?

Set B, pages 406-408

Make a line graph for the data. Use grid paper to draw a coordinate grid. Label the axes.
Number each axis with a consistent scale.
Plot the ordered pairs and connect the points.

Remember that line graphs show data that change over time.
Question 1.
Make a line graph for the data Question 2.
Describe the trend. Set C, pages 410–411

Graph the equation y = x + 2.
Choose values for x and find the values for y. y = x + 2
0 = -2 + 2
2 = 0 + 2
5 = 3 + 2
Use grid paper to draw a coordinate grid.
Label and number the axes.
Plot the ordered pairs and connect the points. Remember to choose at least three values for x. The values for x and y must satisfy the equation.

Make a table of values for each equation. Then graph the equations on a coordinate grid.
Question 1.
y = x – 4 Question 2.
y = 3x Question 3.
y = x + 5 Question 4.
y = x  Barb has 3$$\frac{1}{4}$$ ft of ribbon left over. She used 2$$\frac{1}{4}$$ ft to wrap a gift and $$\frac{3}{4}$$ ft to decorate a picture frame. She then used 1$$\frac{3}{4}$$ ft for hair ribbons. How many feet of ribbon did Barb start with?
