What is the slope-intercept form of a linear equation?

Back

The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you graph a linear inequality like y ≥ 2/3x + 5?

Back

Plot the line y = 2/3x + 5 using a solid line and shade above the line.

The solution is x = 50.

Front

What does it mean for a line to be 'solid' when graphing inequalities?

Back

A solid line indicates that points on the line are included in the solution set.

Front

What does it mean for a line to be 'dashed' when graphing inequalities?

Back

A dashed line indicates that points on the line are not included in the solution set.

Front

What is the first step in solving a linear equation?

Back

The first step is to isolate the variable on one side of the equation.

Front

What is the definition of a variable in algebra?

Back

A variable is a symbol, often a letter, that represents an unknown value.

Front

What is the purpose of combining like terms in an expression?
