Linear Equation Vocab

Front

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

Back

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that as x increases, y also increases, meaning the line rises from left to right.

Front

How is slope defined?

Back

Slope is described as 'rise over run', which represents the change in y over the change in x.

Front

What is the definition of a function?

Back

A function is a relation where each x-value can only correspond to one y-value; x-values cannot repeat.

Front

Which slopes indicate perpendicular lines?

Back

Front

Back

The y-intercept is the value of y when x is 0, represented by b in the equation.

Front

What does the term 'rise' refer to in slope?

Back

'Rise' refers to the vertical change between two points on a line.

Front

What does the term 'run' refer to in slope?

Back

'Run' refers to the horizontal change between two points on a line.

Front

If a line has a slope of 0, what does that indicate?

Back

A slope of 0 indicates a horizontal line, meaning there is no change in y as x changes.

Front

If a line has an undefined slope, what does that indicate?

Back

An undefined slope indicates a vertical line, where x remains constant while y changes.
