Area of triangle is 1/2 times base times height
lets say the base is from x1,y2 to x1,y1 the distance is 6 units
1/2 times 6 times height
from x1,y1 to x3,y3 is 7 units to the right
1/2 times 6 times 7=3 itmes 7=21
area=21 square units or
21 units^2
Answer:
4th choice (if we guessed the blurry letters properly)
Step-by-step explanation:
The reflection maps ...
(x, y) ⇒ (x -y)
Then the rotation maps ...
(x, -y) ⇒ (y, x)
That is, R(-1, 4) becomes R'(4, -1), apparently matching point S, the only point at (4, -1). We can't read the letters, but we know that you only need to know where R ends up in order to select the correct answer.
