Slope and y-intercept

Front

What is the y-intercept of a line?

Back

The y-intercept is the point where the line crosses the y-axis.

Front

What does the slope of a line represent?

Back

The slope represents the steepness of the line, indicating how much y changes for a change in x.

Front

In the equation y = mx + b, what does 'm' stand for?

Back

'm' represents the slope of the line.

Front

In the equation y = mx + b, what does 'b' represent?

Back

'b' represents the y-intercept of the line.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.

Front

How do you calculate the slope between two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What is the slope in the equation y = 2x + 5?

Back

The slope is 2.

Front

If a line has a slope of -3, what does this indicate about the line?

Back

The line descends from left to right.

Front

What is the formula for the slope-intercept form of a line?

Back

The formula is y = mx + b.
