the answer when subtracting
difference
To multiply out the parts of an expression. Distributing is the opposite of factoring.
Distribute
Perpendicular lines have slopes that are negative reciprocals
perpendicular
The span of numbers found by subtracting the smallest number from the highest number in a set
range
The number in front of a variable
coefficient
The difference in y values divided by the difference of x values. Also known as rise over run.
slope
The point where the graph crosses the Y axis (there is a dash in the answer)
Y-intercept
The point or points where graphs "touch"
intersection
On the coordinate plane, the pair of numbers giving the location of a point (ordered pair).
coordinate
The set of values of the independent variable(s) for which a function or relation is defined. Typically, this is the set of x-values
domain
Can be linear, quadratic, absolute value, exponential, inequality, etc.
function
less than, greater than, less than or equal to, greater than or equal to
inequality
the answer when you divide
quotient
The highest value in a set or on a graph.
maximum
To plug in a number and evaluate (check)
substitute
An unknown number usually represented by a letter.
variable
the answer when you add
sum
the answer when you multiply
product
The longest side of a right triangle. This side is across from the right angle.
hypotenuse
To reduce or put in simplest terms.
simplify
The point or points where the graph of a quadratic function hits the x-axis. These are also called zeros.
root
A straight line that shows a constant rate of change.
linear
In order
Consecutive
To explain an answer or solution
Justify
A math sentence that contains an equal sign
equation
