Flashcard 4/5 Qt. 2 Three ways to find slope

Front

What is the slope of the line represented by the equation Y = -8X + 5?

Back

Slope is -8.

Front

What is the slope of the line represented by the equation Y = 6X - 7?

Back

Slope is 6.

Front

How do you calculate the slope using two points (6, -14) and (4, -8)?

Back

Slope = (y2 - y1) / (x2 - x1) = (-8 - (-14)) / (4 - 6) = 6 / -2 = -3.

Front

If the rise is 20 and the run is -4, what is the slope?

Back

Slope = rise/run = 20 / -4 = -5.

Front

If the rise is 12 and the run is 3, what is the slope?

Back

Slope = rise/run = 12 / 3 = 4.

Front

What is the formula for calculating slope?

Back

Slope (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

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.
