Linear Equations and Slope

Front

What is the definition of slope?

Back

The change in the y value over the change in the x value.

Front

Convert y - 8 = 2/5(x + 5) to slope-intercept form.

Back

y = 2/5x + 10

Front

What is the slope of a vertical line?

Back

undefined

Front

Rise / Run is used for what?

Back

Finding the slope of a line.

Front

The slope of this line is: positive, undefined, zero, or negative?

Back

negative

Front

What is the slope of a horizontal line?

Back

zero

Front

What does a positive slope indicate about a line?

Back

The line rises from left to right.

Front

What does a negative slope indicate about a line?

Back

The line falls from left to right.

Front

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

Back

y = mx + b, where m is the slope and b is the y-intercept.

Front

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

Back

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