Dilate line f by a scale factor of 2 with the center of dilation at the origin to create line f. Where are points A' and B' loca

V125BC [204]

Answer:

Option A

Step-by-step explanation:

We are given that

Scale factor=2

Center of dilation=(0,0)

Point A(0,2) and point B (2,0).

Slope of line f= $\frac{y_2-y_1}{x_2-x_1}$

Substitute the values

Slope of line f= $\frac{0-2}{2-0}=-1$

Distance between A and Origin (0,0) is given by

$OA=\sqrt{(0-0)^2+(0-2)^2}=2 units$

Using distance formula

$\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

OB= $\sqrt{(0-2)^2+(0-0)^2}=2 units$

Length of OA'=2OA=2(2)=4 units

Length of OB'=2(OB)=2(2)=4 units

x-intercept of line f' at x=4

y-intercept of line f' at y=4

Therefore, the points A' and B' are given by

(0,4) and (4,0)

Slope of line f'= $\frac{0-4}{4-0}=-1$

Slope of line f and f' are equal.Therefore, lines f and f' are parallel.

Option A is true.
