Select the graph that demonstrates an association in which the y-value increases as the x-value increases, data points that go generally upward from left to right.
Select the graph that demonstrates an association in which the y-value decreases as the x-value increases, data points that go generally downward from left to right.
Select the graph that demonstrates when there is no pattern in the observed data.
Select the graph that demonstrates when the data points are clustered close together, not spread out; the M.A.D. is smaller.
Select the graph that demonstrates when the data points are clustered loosely, more spread out; the M.A.D. is bigger.
Select the graph that demonstrates an association in which the data appear to lie close to a line.
Select the graph that demonstrates when data points do not lie close to a straight line, more like a curve.
Select the graph that demonstrates a line on a scatterplot that helps show the association between data sets more clearly, used to make predictions, also called a line of best fit.
Graph
Use the drop down menus to correctly define the term. Mean absolute deviation is the (a) distance between each data value and the (b) .
Use the drop down menus to correctly define the term. A scatterplot is a graph that shows the relationship between a data set with (a) variables, graphed as (b) on (c) .
Select the correct term to fill in the blank of the definition.
A (a) is a letter or symbol used in place of unknown numbers or quantities in expressions, equations, and inequalities (most common are x and y).
The (b) are any value(s) that makes an equation/number sentence or inequality true when substituted for the unknown(one, no, infite).
A multiplicative (multiplying) factor of a variable term (the number in front of the variable is called a (c) .
(d) is the interest earned on both the principal amount and any interest already earned.
The amount borrowed or the amount still owed on a loan; represented by the variable, P, is called (e)
Match the term to the correct definition
a number representing a fixed value (a rational number;does not appear with a variable)
constant
money paid only on principal, or money borrowed or invested
simple interest
total amount in the account which is the principal and interest combined
account balance
extra money paid for a loan(cost) or the extra amount received from an investment(earned)
interest
mathematical operations that allow us to "undo" operations on a variable in order to isolate the variable and determine its numberic value
inverse operations
The output; can take on different values only in response to its corresponding, independent quantity/variable.
run
rise
independent variable
dependent variable
The input; does not depend on another quantity or variable, but rather causes corresponding changes to the dependent quantity.

A transformation is a mapping or movement of a geometric figure that changes its location, orientation OR size.
True
False
The pre-image is the position of a figure AFTER a transformation has been completed.
True
False
The image is the position of a figure BEFORE a transformation has been completed.
True
False
For a reflection, each point of the original figure (pre-image) has an image point that is the same distance from the line of reflection as the original point but on the opposite side of the line; a transformation in which a figure flips over a line of symmetry.
True
False
When the pre-image and image have different side lengths(size) AND the different angle measures(shape), the transformation preserves congruence.
True
False
