What is a line of best fit?
A line that describes the trend in data.

What is the name for the y = mx + b form of a line?
slope - intercept form
100
The name of a shape with three sides.
Triangle

This word means "the same size and shape." We call two angles this when their measurements are equal to each other.
Congruent

What does an r value tell you?
How strongly the data is correlated, and whether the trend is directly or inversely correlated.
200
What does the slope of a line represent?
The slope represents the rate of change.

What would the scatterplot of data which has no association look like?
Data points all around, with no clear pattern.
300
What does the y - intercept represent?
Usually, the y intercept represents a starting point. More generally, it is the y value when the x value is 0.

3n + 0 = 9
What is the value of n?
n = 3

Does every line have a slope - intercept form?
YES! All linear equations can be re-written into slope intercept form...
