Front

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

Back

The slope of a line perpendicular to a line with slope -3 is \frac{1}{3}.

Front

Write the equation of a line perpendicular to y = -3x + 1 that passes through (3, -1).

Back

The equation is y = \frac{1}{3}x - 2.

Front

What is the slope of the line that contains point (-2,2) and is perpendicular to x - 2y = 5?

Back

The slope is -2.

Front

Are the lines y = \frac{1}{2}x + 2 and y = -2x + 13 perpendicular?

Back

Yes, they are perpendicular.

Which equation passes through (-1, 6) and is perpendicular to y = 7?

Back

The equation is x = -1.

Front

Which equation is perpendicular to x = 7 and passes through (-4,9)?

Back

The equation is y = 9.

Front

What is the relationship between the slopes of two perpendicular lines?

Back

The product of their slopes is -1.

Front

If a line has a slope of 2, what is the slope of a line perpendicular to it?

Back

The slope of the perpendicular line is -\frac{1}{2}.

Front

How do you find the slope of a line given two points (x1, y1) and (x2, y2)?

Back

The slope m is given by m = \frac{y2 - y1}{x2 - x1}.

Front

What is the slope-intercept form of a line?

Back

The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.
