Answer:
The coordinates of STUV after using the given rule (x,y) -------> (x+1,y-4) are
S'(8,-8)
T'(11,-8)
U'(11,2)
V'(8,2)
Explanation:
Given rule is (x,y) -------> (x+1,y-4)
The coordinates of STUV are given
S(7,4) ,T(10,4) , U(10,6) and V(7,6)
To find the coordinates of STUV after applying the given rule
(x,y) -------> (x+1,y-4) :
Put x=7 and y=4 in the given rule
S(7,4) ------> S'(7+1,-4-4) =S'(8,-8)
Therefore S(7,4) ------>S'(8,-8)
Put x=10 and y=-4 in the given rule
T(10,-4) ------> T'(10+1,-4-4) =T'(11,-8)
Therefore T(10,-4) ------> T'(11,-8)
Put x=10 and y=6 in the given rule
U(10,6) ------> U'(10+1,6-4) =U'(11,2)
Therefore U(10,6) ------> U'(11,2)
Put x=7 and y=6 in the given rule
V(7,6) ------> V'(7+1,6-4) =V'(8,2)
Therefore V(7,6) ------> V'(8,2)
Therefore the coordinates of STUV after using the given rule
(x,y) -------> (x+1,y-4) are
S'(8,-8)
T'(11,-8)
U'(11,2)
V'(8,2)
