Question

If triangle abc has verticies a (1,2), b(-1,-1), and c(0,-2), which of the following coordinates is b of the dilation using the scale factor of 4

Answer 1

(-4,-4)

Explanation:

Given

a (1,2), b(-1,-1), and c(0,-2)

Scale factor = 4

Required

Find the coordinates of b

Let the new coordinates of b be represented by b'

b' = b * scale factor

where b = (-1,-1)

scale factor = 4

b' = 4 * (-1,-1)

b' = (4*-1, 4 * -1)

b' = (-4,-4)

Hence, the new coordinates of b is (-4,-4)
