Slope Intercept Form

Front

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

Back

y = mx + b

Front

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

Back

The slope of the line.

Front

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

Back

The y-intercept of the line.

Front

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

Back

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

Front

What is the slope of the line represented by the equation y = -2x + 5?

Back

The slope is -2.

Front

What is the y-intercept of the line represented by the equation y = 3x - 4?

Back

The y-intercept is -4.

Front

How do you convert the standard form of a line Ax + By = C to slope-intercept form?

Back

Solve for y to get y = (-A/B)x + (C/B).

Front

If the slope of a line is 0, what does that indicate about the line?

Back

The line is horizontal.

Front

If the slope of a line is undefined, what does that indicate about the line?

Back

The line is vertical.
