What is the meaning of the y-intercept?

Back

The y-intercept is the point where a line crosses the y-axis, indicating the value of y when x is 0.

Front

What is the y-intercept of the graph (0,1)?

Back

The y-intercept is (0,1), meaning the line crosses the y-axis at 1.

Front

What is the equation of the line that is vertical?

Back

The equation of a vertical line is in the form x = a, where 'a' is the x-coordinate of any point on the line.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0, indicating no change in y as x changes.

Front

What is the y-intercept of the line graphed at 4?

Back

The y-intercept is 4, meaning the line crosses the y-axis at 4.

Front

What does a slope of 1 indicate?

Back

A slope of 1 indicates that for every unit increase in x, y increases by the same amount.

Front

What does a negative slope indicate?

Back

A negative slope indicates that as x increases, y decreases.

Front

What is the formula for calculating slope?

Back

The formula for slope (m) is m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are two points on the line.

Front

What does the point (0,0) represent on a graph?

Back

The point (0,0) is the origin, where the x-axis and y-axis intersect.

Front

What is the significance of the x-intercept?

Back

The x-intercept is the point where a line crosses the x-axis, indicating the value of x when y is 0.
