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

What does 'm' represent in the equation y = mx + b?

Back

'm' represents the slope of the line.

Front

What does 'b' represent in the equation y = mx + b?

Back

'b' represents the y-intercept, the point where the line crosses the y-axis.

Front

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

Back

The slope (m) is calculated as m = (y2 - y1) / (x2 - x1).

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.

Front

If a line has a slope of 2, what does this mean?

Back

For every 1 unit increase in x, y increases by 2 units.

Front

What does it mean if two lines are parallel in terms of slope?

Back

Parallel lines have the same slope.

Front

What does it mean if two lines are perpendicular in terms of slope?

Back

Perpendicular lines have slopes that are negative reciprocals of each other.

Front

How can you determine if a linear function is increasing or decreasing?

Back

If the slope (m) is positive, the function is increasing; if negative, it is decreasing.
