Atransformation t : (x, y) (x + 3, y + 1).
the image of b(4, 1) under this transformation is

(7, 2)
(1, 0)
(-1, 0)

A transformation

is a translation 3 units to the right and 1 unit up.

To find the image of point B(4,1), you have to substitute 4 instead of x and 1 instead of y into the transformation rule:

Then the image point has coordinates (4+3,1+1) that is (7,2).

correct choice is A

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
