idk read the question

Answer 7

can some one help plz

Answer 8

this is the rule they give you:

(x, y)→(x−7.5, y+6.8)

this means take the x-coordinate, subtract 7.5
also, take the y-coordinate and add 6.8

I'll show you how to do the first input, and let you try the second input on your own

First input: (5.3, 2.7)
x-coordinate is 5.3 ---> subtract 7.5 ---> 5.3 - 7.5 = ?
y-coordinate is 2.7 ---> add 6.8 ----> 2.7 + 6.8 = ?

calculate. then repeat with the second input

Answer 9

for x is -2.2 and y is 9.5

Answer 10

good, that's the output for the first input

can you try with the second input now?

Answer 11

ok let me try

Answer 12

having some trouble?

the second input is (9.4, -3.9)

our rule: (x, y)→(x−7.5, y+6.8). subtract 7.5 from x. add 6.8 to y.

so we have:
x: 9.4 - 7.5 = ?
y: -3.9 + 6.8 = ?

Answer 13

yea that want im doing

Answer 14

ok x is 1.9 and y is 2.9

Answer 15

good, so (1.9,2.9) is the output for the second input
