Real numbers
what are real numbers
numbers that include both rational and irrational numbers. Rational numbers such as integers (-2, 0, 1), fractions(1/2, 2.5) and irrational numbers such as √3, π(22/7), etc., are all real numbers.
What are linear equations?
an algebraic equation of the form y=mx+b. involving only a constant and a first-order (linear) term, where m is the slope and b is the y-intercept.
What is a function?
a relationship between inputs where each input is related to exactly one output.
What is the pythagoreom theorem
Helps us find the missing side length of a right triangle.
whats not a real number ?
imaginary number
What is a linear equation example?
2x – 3 = 0
2y = 8
m + 1 = 0
x/2 = 3
x + y = 2 3x – y + z = 3
What is not a function
Vertical lines
How do you set up pythagroem theorem
a^2+b^2=c^2
Yes, decimal numbers are real numbers.
Simple explanation of a linear
a function that has either one or two variables without exponents.
How to identify a function
check to see if any of the x values are repeated - if not, it is a function.
Can you solve the Pythagorean theorem with only C?
5 types of real numbers
There are 5 classifications of real numbers: rational, irrational, integer, whole, and natural/counting
How do you set up a linear equation
2a+2b=2c
what is an example of what is a fuction and what isnt a fuction
when can you not use pythagoreom theorem
When the triangle is not a right triangle
What is the difference between a real number and an integer?
Integers are a type of real number that just includes positive and negative whole numbers and natural numbers.
3 forms of linear equations
point-slope form
standard form
slope-intercept form
Example of a function in real life
the distance a car has traveled (the output) is dependent on how long that car has been driving (the input)

What is C called in pythagoreom theorem
