Practice C continued
For use with the lesson “Identify Points, Lines, and Planes”
You are given an equation of a line and a point. Use substitution to
determine whether the point is on the line.
21. y 5 3x 1 7; A(2, 13)
22. y 5 4x 2 3; A(5, 17)
23. 2y 5 23x 2 9; A(21, 23)
24. 5x 1 4y 5 28; A(4, 22)
25. 6y 2 7x 5 8; A(6, 4)
26. 22x 2 9y 5 220; A(28, 4)
Graph the inequality on a number line. Tell whether the graph is a
segment, a ray or rays, a point, or a line.
27. x ≥ 6
28. x ≤ 210
31. x ≥ 0 or x ≤ 22
32. x 2 ≤ 0
Lesson 1.1
30. x ≥ 7 or x ≤ 4
29. 25 ≤ x ≤ 3
In Exercises 33–35, use the following information.

Perspective Drawing A perspective drawing is drawn using vanishing points, as
described in the text. The figure below is a perspective drawing of a garage.
33. Draw the lines necessary to locate the two vanishing points.
34. Using the two vanishing points, draw the lines necessary to show the hidden lines of
the garage.
35. Using heavy dashed lines, draw the hidden lines of the garage.
