the translation takes the point A ( -1, -1) to (-1+4, 1) = (3, 1)
The refection in y = x 'flips' the points so (3, 1) becomes (1, 3) = A"
Do the same procedure for the other points to get the answer
(you should get B" = (-3, 3) )
So, she has 550 dollars saved. If the junior season pass costs 315, you subtract that from 550. You should then have 235 dollars. Next, you divide 235 by 45 dollars per lesson, and you should get 5.22. You can't buy half a lesson, so she only has enough for 5 lessons.
H = 1st row 4 -2 5
2nd row 6 1 -3
J = 1st column 7 3 8
1st row and 1st column: 4*7 + -2*3 + 5*8 = 28 - 6 + 40 = 62
2nd row and 1st column: 6*7 + 1*3 + -3*8 = 42 + 3 - 24 = 21
Answer is 2nd option. 62 and 21.
