Mastering Linear Functions and Equations

A mathematical sentence that contains an equal sign

A mathematical sentence without an equal sign

A mathematical sentence that describes a function

A mathematical sentence that contains an inequality symbol

By adding the variables together

By subtracting one variable from the other

By dividing both sides by the coefficient of the variable

By getting variables on the same side and simplifying

b = mx + y

y = mx + b

mx - b = y

y - mx = b

x2 - x1 + y2 - y1

(y2 - y1) / (x2 - x1)

(y1 - y2) / (x1 - x2)

(x2 - x1) / (y2 - y1)

Graphing

Elimination

Matrix

Substitution

Graphing both equations

Finding the slope

Eliminating one variable

Setting one equation equal to a variable

To graph linear inequalities

To find the slope of a line

To determine if a graph represents a function

To solve linear equations

The intercepts of the graph

The slope of the graph

The x-values of a graph

The y-values of a graph

a_n = d(a_1 + n - 1)

a_n = a_1d^n

a_n = a_1 + d/n

a_n = a_1 + (n - 1)d

The product of the first and last term

The difference between consecutive terms

The sum of all terms divided by the number of terms

The difference between the first and last term
