SLOPE PRACTICE-HONORS

Front

What is the formula to calculate the slope between two points (x1, y1) and (x2, y2)?

Back

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

Front

If the slope of a line is positive, what does that indicate about the line's direction?

Back

The line rises from left to right.

Front

What does a slope of zero indicate about a line?

Back

The line is horizontal.

Front

What does an undefined slope indicate about a line?

Back

The line is vertical.

Front

Calculate the slope between the points (1, 3) and (5, 11).

Back

m = 2.

Front

If a line has a slope of -3, what does that indicate about the line's direction?

Back

The line falls from left to right.

Front

What is the slope of a line that goes through the points (2, 4) and (2, 8)?

Back

The slope is undefined.

Front

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

Back

For every 2 units you move horizontally (run), you move 1 unit vertically (rise).

Front

Find the slope of the line represented by the equation y = 3x + 2.

Back

The slope is 3.

Front

What is the slope of a line that is perfectly horizontal?

Back

The slope is 0.
