pythagorean theoreum

c2 = a2 + b2

Division

the inverse of multiplication

M

the letter that represents the slope in y = mx + b

Binomial

two terms connected by + or -

subtract

when dividing the same base, do this with the exponents

solid line

when graphing a linear inequality, if it is equal to use this

add

when multiplying the same base, do this with the exponents

No Solution

when you eliminate the variable in a equation and what's left is not true

multiply

when you have an exponent outside the parentheses and one inside, you so this with the exponents

point slope equation

y - y = m(x-x)

slope intercept equation

y=mx+b

polynomial

Positive

a line that goes uphill has this type of slope

Expression

a mathematical phrase that does not contain an =

coefficient

a number attached to a variable by multiplication

Factor

a number involved in multiplications

Right Triangle

a triangle with one 90 degree angle.

Constant

a value that does no change

Identity

an equation that is true for every possible value of the variable

Infinitely Many

Scientific Notation

the product of two numbers, one greater than or equal to one but less than ten, the other a power of ten

Hypotenuse

the side across from the right angle in a right triangle

Zero

the slope of a horizontal line.

Undefined

the slope of a vertical line.

Least common multiple

the smallest number that is a multiple of two or more exponents

Intersect

the solutions in a system of equations represent where the lines do this

The same

the solutions of the first compared to the second in a system of equations

Slope
