Find the image of Y(-7,4) after a dilation centered at the origin with a scale factor of -3

F= Y(-21,12)
G=Y(12,-21)
H=Y(21,-12)
J=Y(-12,21)

Respuesta :

Answer:

H = Y (21, -12)

Step-by-step explanation:

Given

  • Y = (-7, 4)
  • Dilation of -3

Solving

  • Multiply the x-value and y-value of the coordinate by -3
  • Y = (-7 x -3, 4 x -3)
  • Y = (21, -12)

The required image point is H=Y(21, -12)

What will happened with scale factor ?

If the scale factor is given then by multiplying the scale factor with the co-ordinates gives us the image of the given point.

How to find the required image point ?

Here the given point is Y(-7, 4)

After the dilation centered at origin, the scale factor is -3

∴ The x co-ordinate is (-7)×(-3)=21

& the y co-ordinate is 4×(-3)= -12

Hence the image is Y(21, -12)
