Finding Slope From a Graph

Front

What is the slope of a horizontal line?

Back

0 (Zero)

Front

What is the slope of a vertical line?

Back

Undefined

Front

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

Back

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

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 of the line represented by the equation y = 4x + 2?

Back

4

Front

What is the slope of the line represented by the equation y = -2x + 3?

Back

-2

Front

If a line has a slope of 1/2, what does this mean in terms of rise and run?

Back

For every 2 units you move right (run), the line rises 1 unit.

Front

What is the slope of the line that passes through the points (1, 2) and (3, 6)?

Back

2

Front

What is the slope of the line that passes through the points (2, 3) and (2, 5)?

Back

Undefined (vertical line)
