Formulas
y=mx+b
What is the slope intercept formula?
A data point far from most of the other data points (ex:2, 3, 4, 5, 6, 8, 8, 40. 40 is an_____)
What is an outlier?
Starting from the top left down to the bottom right. \
What does a negative slope look like?
An angle less than 90 degrees but greater than 0 degrees.
Any value is equal to itself.
What is the Reflexive property?
Rise/Run=y2-y1/x2-x1=Change in y over change in x
What is the slope formula?
The middle number in a data set. If there is an even number then it is the mean of the two middle numbers.
What is a median?
Starting from the bottom left up to the top right. /
What does a positive slope look like?
An angle greater than 90 degrees but less than 180 degrees.
What is an obtuse angle?
States that an equation can be written two ways with both sides interchanged. (If a=b, b=a.)
What is the Symmetric property of equality?
a2+b2=c2
What is the Pythagorean Theorem formula?
The maximum value minus the minimum value. (Ex: 15, 17, 18, 24, 26. ______=26-15=11)
What is range?
Y values don't change. -
What does zero slope look like?
A 90 degree angle.
What is a right angle?
If two numbers or variables are equal to the same number, then they are also equal to each other. Take out the middleman. (a=b, b=c. a=b=b=c. a=c)
What is the transitive property?
(x1+x2/2, y1+y2/2)
What is the midpoint formula?
The most frequent data point. Possible to have more than one or none at all. (Ex: 15, 17, 18, 24, 26. No ______.)
What is mode?
X values don't change. |
What does an undefined slope look like?
An 180 degree angle.
What is a straight angle?
if x=y, then x can be substituted in for y in any equation, and y can be substituted for x in any equation. (x=y and the equation we have is x+5=7, substitute y for x and write the equation y+5=7)
What is the substitution property of equality?
√(x2-x1)2+(y2-y1)2
What is the distance formula?
The sum of all values divided by the total number of values.
What is a mean?
A 360 degree angle.
What is a full rotation angle?
