Slope-intercept

Front

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

Back

The slope-intercept form is given by the equation y = mx + b, where m is the slope and b is the y-intercept.

Front

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

Back

The 'm' represents the slope of the line.

Front

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

Back

The '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 find the slope between two points (x1, y1) and (x2, y2)?

Back

The slope (m) is calculated using the formula m = (y2 - y1) / (x2 - x1).

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that the line rises as it moves from left to right.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that the line falls as it moves from left to right.

Front

If the equation of a line is y = 2x + 1, what is the y-intercept?

Back

The y-intercept is 1.

Front

If the slope of a line is 3, what does this mean in terms of rise over run?

Back

It means that for every 3 units the line rises, it runs 1 unit to the right.
