P2 & P6 - 2nd Quarter Test

Front

What is the result of translating the point (-9, 3) 4 units down and 3 units right?

Back

(-6, -1)

Front

What is the translation rule for moving a point 5 units to the right and 4 units down?

Back

(x + 5, y - 4)

Front

What is the rule for reflecting a point across the line x = 3?

Back

The x-coordinate is transformed as x' = 6 - x.

Front

Which equation is parallel to the line y = -\frac{7}{3}x + 5?

Back

y = -\frac{7}{3}x - 8

Front

What are the slopes of perpendicular lines?

Back

They are opposite reciprocals.

Front

What happens to the coordinates of a point when it is reflected across the y-axis?

Back

The x-coordinate changes sign: (x, y) becomes (-x, y).

Front

What is the slope of a line that is vertical?

Back

The slope is undefined.

Front

What is the slope of a line that is horizontal?

Back

The slope is 0.

Front

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

Back

Slope = \frac{y2 - y1}{x2 - x1}.

Front

What is the transformation rule for a reflection across the x-axis?

Back

The y-coordinate changes sign: (x, y) becomes (x, -y).
