Parallel and perpendicular slopes

Front

What are the slopes of parallel lines?

Back

Identical.

Front

What are the slopes of perpendicular lines?

Back

Opposite reciprocals.

Front

Write the equation in slope-intercept form: y = 2x + 6

Back

The slope is 2 and the y-intercept is 6.

Front

What is the starting term (a) in the function: f(x) = 300(1.16)^x?

Back

300.

Front

Find the slope of a line parallel to the line: y = ½x + 4.

Back

1/2.

Front

What is the slope of a line that is perpendicular to a line with a slope of 3?

Back

-1/3 (opposite reciprocal of 3).

Front

If two lines have slopes of 2 and -1/2, are they parallel, perpendicular, or neither?

Back

Perpendicular (opposite reciprocals).

Front

What is the slope of a horizontal line?

Back

0.

Front

What is the slope of a vertical line?

Back

Undefined.

Front

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

Back

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