Basic Vocab
The symbol (or letter) that represents an unknown quantity.
What is a variable?
A two-dimensional plane formed by the intersection of two number lines (the x and y-axis). It has 4 quadrants.
What is a coordinate plane?
The point where the graph intersects the y-axis. Also called the initial value.
What is the y-intercept?
In a system of equations, two linear functions that intersect at one point.
What is ONE SOLUTION?
A single number or variable or a number multiplied by a variable. They are separated by '+' or '-'.
What is a term?
The horizontal number line on the coordinate plane.
What is the x-axis?
The steepness of a line (change in y over change in x). Also known as the rise /run.
What is the slope?
In a system of equations, two linear functions that do not intersect (parallel lines).
What is NO SOLUTION?
A number that shows how many times a number is multiplied by itself.
What is an exponent?
The vertical number line on a coordinate plane.
What is the y-axis?
The equation of a straight line where m represents the slope and b represents the y-intercept.
What is slope-intercept form?
What are the three methods for solving systems of equations?
What are GRAPHING, ELIMINATION and SUBSTITUTION?
The number that gets multiplied when using an exponent.
What is a base?
Where the x-axis and y-axis intersect. Point (0, 0).
What is the origin?
A linear equation where x and y represent variables and A, B and C represent numbers.
What is standard form?
In a system of equations, two linear functions with the same slopes and intercepts.
What is INFINITELY MANY SOLUTIONS?
