Slope Intercept Form

Front

What does 'b' represent in the slope-intercept form of a linear equation (y = mx + b)?

Back

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

Front

How do you calculate 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 is the slope of a horizontal line?

Back

The slope of a horizontal line is zero.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.

Front

What does a positive slope indicate about a line?

Back

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

Front

What does a negative slope indicate about a line?

Back

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

Front

In the equation y = 5x - 6, what is the slope?

Back

The slope is 5.

Front

What is the general form of a linear equation?

Back

The general form of a linear equation is Ax + By = C.

Front

What does it mean if a linear function's graph is straight?

Back

It means that the relationship between the variables is linear, and can be described by a linear equation.

Front

How can you identify the y-intercept from the slope-intercept form of a linear equation?

Back

The y-intercept is the value of 'b' in the equation y = mx + b.
