slope intercept form

Front

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

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

If the slope (m) is 2 and the y-intercept (b) is -3, what is the slope-intercept equation?

Back

y = 2x - 3

Front

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

Back

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

Front

What is the slope of the line represented by the equation y = -4x + 5?

Back

-4

Front

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

Back

The line is horizontal.

Front

If a line has an undefined slope, what does that indicate about the line?

Back

The line is vertical.

Front

Back

3

Front

How can you determine if two lines are parallel using their slope?

Back

If two lines have the same slope, they are parallel.
