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
