A triangle with point (8, 10) undergoes a dilation with a scale factor of 1/2. What are the new coordinates of the point?

Respuesta :

Answer:

(4, 5)

Step-by-step explanation:

Answer:

New x-coordinate: 4

New y-coordinate: 5

New point: (4,5)

Step-by-step explanation:

You know that the coordinates of a point of this triangle are the following:

[tex]x_1=8\\y_1=10[/tex]

And you know that it is dilated with a scale factor of [tex]\frac{1}{2}[/tex], then, to find the new coordinates of the point, you need to multiply the original coordinates by the scale factor:

New x-coordinate:

[tex]x_2=\frac{1}{2}x_1[/tex]

[tex]x_2=\frac{1}{2}(8)[/tex]

[tex]x_2=4[/tex]

New y-coordinate:

[tex]y_2=\frac{1}{2}y_1[/tex]

[tex]y_2=\frac{1}{2}(10)[/tex]

[tex]y_2=5[/tex]

The new point is (4,5)
