Reflection across the x-axis

Keep x-value the same, take the opposite of new y-value [Example: (3, 2)  (3, -2)]

Translations

: If given a rule, use the coordinates given and “plug” them in for the x and y in the second part of the rule [Example: Rule: (x, y)  (x – 10, y + 4), Coordinate given: (3, 2); (3 – 10, 2 + 4) = (-7, 6)] -If given “directions”, remember “left” and “right” affect the x-value. “Up” and “Down” affect the y-value

<p>: If given a rule, use the coordinates given and “plug” them in for the x and y in the second part of the rule [Example: Rule: (x, y)  (x – 10, y + 4), Coordinate given: (3, 2); (3 – 10, 2 + 4) = (-7, 6)] -If given “directions”, remember “left” and “right” affect the x-value. “Up” and “Down” affect the y-value</p>

Dilations

multiply both the x and y values by the scale factor (k) given. [Example: k = 3, coordinate given (3, 2) (9, 6) or k = ½ , coordinate given (3, 2)  (1.5, 1)]

<p>multiply both the x and y values by the scale factor (k) given. [Example: k = 3, coordinate given (3, 2) (9, 6) or k = ½ , coordinate given (3, 2)  (1.5, 1)]</p>
