| Unit 4 Skills Review |
[Back] |
You will be required to demonstrate a mastery of the following skills on the Unit 4 Test.
| 1) | Recognize and
GRAPH horizontal and vertical lines in the coordinate plane, such as: x=3,
y=-5. See the supplemental SLOPE Lesson & Linear Equation Lesson |
|||||||||||||||||||
| 2) | Complete a
table of values for a linear equation and sketch the line, such as:
|
|||||||||||||||||||
| 3) | Find the x-
and y-intercepts for a linear equation and sketch the line, using the
thumb cover-up" method with "intercepts" form:
|
|||||||||||||||||||
| 4) | Find the slope
of a line through two points, graphically (up & over) and by the
slope formula:
|
|||||||||||||||||||
| 5) | Given two points in the coordinate plane, find the slope of the line through those points. Recognize the slopes of "special" lines: horizontal (slope = 0) and vertical (slope undefined). | |||||||||||||||||||
| 6) |
Rewrite linear equations in slope-intercept form:
|
|||||||||||||||||||
| 7) | Find the vertex and GRAPH absolute value equations in two variables in the coordinate plane using a table of values. Such as: | |||||||||||||||||||
| 8) | Know how to
find the vertex of an absolute value equation without graphing.
Also, know how to determine whether an absolute value equation will
graph "v" up or down without graphing. Hint:
What value of the variable "forces" the expression inside the
abs-val brackets to ZERO??
