Answer:
7) Option A
10) Option J
Explanation:
7). From the graph attached,
Coordinates of S → (-5, 6)
Coordinates of U → (2, -6)
If the given points are reflected by the rule,
(x, y) → (-x, y)
[Change the sign of x - coordinates of S and U]
Coordinates of S' → (5, 6)
Coordinates of U' → (-2, -6)
Option A will be the answer.
10). Coordinates of the vertices of the ΔXYZ,
X → (6, 9)
Y → (9, 5)
Z → (4, 5)
If the vertices of this triangle are translated 3 units left and 4 units down,
Rule for the image points will be,
(x, y) → (x - 3, y - 4)
By this rule coordinates of the image points will be,
X(6, 9) → X'(3, 5)
Y(9, 5) → Y'(6, 1)
Z(4, 5) → Z'(1, 1)
Therefore, Option J will be the answer.
