1st Semester Vocab Terms Flashcards
Terms that have the same variable raised to the same power. We combine them when simplifying expressions or solving equations.
Like Terms
A mathematical phrase that combines numbers, variables, and arithmetic operations to represent a quantity.
Algebraic Expression
An unknown quantity represented by a letter or symbol whose value can change from one problem to the next.
Variable
A quantity that does not change. It is a number by itself with no variable.
Constant
A number that is multiplied by a variable in an algebraic expression.
Coefficient
A mathematical sentence stating that 2 algebraic expressions are equivalent.
Equation
A mathematical sentence stating that 2 algebraic expressions are NOT equivalent.
Inequality
To find the value of an expression by substituting in known values of the given variables. Another word for “solve”.
Evaluate
Putting a mathematical expression into its least complicated form. To reduce.
Simplify
The measure of the steepness of a line and is calculated by rise/run.
Slope
The point on a graph where the line crosses the x-axis (where y = 0).
X-Intercept
The point on a graph where the line crosses the y-axis (where x = 0).
Y-Intercept
The linear form, Ax + By = C, where A, B, and C are all integers. We use this to find the x and y intercepts.
Standard Form
The linear form, y = mx + b, where m is the slope of the line and b is the y-intercept.
Slope-Intercept Form
The linear form, y - y1 = m(x - x1), where m is the slope of the line that passes through point (x1, y1).
Point-Slope Form
