What is a function? - Correct Answer - Each x must be paired with only one
y value
vertical line test - Correct Answer - If any vertical line passes through no
more than one point of the graph of a relation, then the relation is a
function.
A function can have the same y coordinate, but not the same x coordinate.
- Correct Answer - True
intercept method - Correct Answer - Find the x & y intercepts, Ex: Graph
x+2y=6. Substitute a 0 for y to find the x-intercept. x+2(0)=6 or x=6; X-int
(6,0). Sub 0 for x to find the y-intercept, 0+2x=6 or x=3 (0,3)
Graphing Inequalities - Correct Answer - A solid line means the inequality is
≥ or ≤. A dotted line means the inequality is > or <.
How do you know which side to shade when graphing inequalities? -
Correct Answer - Create a test point (usually (0,0). If the resulting point is
TRUE, Shade the side that includes the test point.
For any flat line, the slope is always: - Correct Answer - m=0
For any vertical line, the slope is always: - Correct Answer - Undefined, no
slope
slope formula - Correct Answer - m=y2-y1/x2-x1
slope-intercept form - Correct Answer - y=mx+b, where m is the slope and
b is the y-intercept of the line.
Commutative Property - Correct Answer - The property that says that two
or more numbers can be added or multiplied in any order without changing
the result.
Associative Property - Correct Answer - The way in which numbers are
