Find The Slope of a Line

Front

What is the formula to calculate the slope of a line?

Back

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

Front

What does 'rise over run' mean in the context of slope?

Back

It refers to the vertical change (rise) divided by the horizontal change (run) between two points on a line.

Front

How do you identify the slope from a graph?

Back

By selecting two points on the line, calculating the rise and run, and then using the formula: slope = rise/run.

Front

What is the slope of a line that rises 3 units for every 2 units it runs?

Back

The slope is 3/2.

Front

If a line goes down from left to right, what can be said about its slope?

Back

The slope is negative.

Front

What is the slope of a horizontal line?

Back

The slope is 0.

Front

What is the slope of a vertical line?

Back

The slope is undefined.

Front

How can you find the slope using two points (2, 3) and (5, 7)?

Back

Slope = (7 - 3) / (5 - 2) = 4/3.

Front

If the slope of a line is -2, what does this indicate about the line's direction?

Back

The line descends from left to right.

Front

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

Back

The slope is 3.
