okay this one and that's all I need.

Triangle ABC has vertices located at A (2,5), B (3, 7) and C (2, 9). If it undergoes the dilation (x,y)--(4x, 4y), list the new coordinates of the vertices.

A’_________B’_________C’__________

Select one:

a.
A' (6, 9) B' (7, 11) C' (6, 13)

b.
A' (1/2, 2) B' (1, 3) C' (1/2, 1)

c.
A' (1, 4) B' (2, 6) C' (4, 2)

d.
A' (8, 20) B' (12, 28) C' (8, 36)

$(x,y) \to (4x,4y)$ means that we've multiplied each x and y coordinate by 4

For example, the point (2,7) becomes (8,28) because
2*4 = 8
7*4 = 28

Use this for the three given points to find their new locations.
