Answer:The image of the point is

(-18, -12)Step-by-step explanation:If the point(x, y)dilated by a scale factorkcentered at theorigin, then its image is(kx, ky)Let us use this rule to solve the question

∵ The given point is

(-6, -4)∴ x = -6 and y = -4

∵ The scale factor of the dilation is 3

∴

k = 3∵ The

centerof dilation is theorigin→ By using the rule above

∴ The image of the point = (-6 × 3, -4 × 3)

∴ The image of the point = (-18, -12)

∴

The image of the point is (-18, -12)
