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

Front

How do you find the slope of a line given two points (x1, y1) and (x2, y2)?

Front

What does it mean for a relation to be a function?

Back

A relation is a function if each input (x-value) corresponds to exactly one output (y-value).

What is the y-intercept of a line?

Back

Front

Given the points (2, 3) and (4, 7), what is the slope of the line connecting them?

Front

What is the equation of a line in slope-intercept form that has a slope of 3 and a y-intercept of -2?

Front

How can you determine if a graph represents y as a function of x?

Back

A graph represents y as a function of x if any vertical line drawn through the graph intersects it at most once (Vertical Line Test).

Front

What is the significance of the slope in a linear equation?

Back

The slope indicates the steepness of the line and the direction it moves: positive slope means the line rises, negative slope means it falls.

Front

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

Back

A slope of 0 indicates a horizontal line, meaning the y-value remains constant regardless of the x-value.
