Pint d is located at (15,30), what are the new coordinates if the point is dilated by 1/3?

a) 15,30

b) 45,90

c) 3,10

d) 5,10

D)   (5, 10)

Explanation:

Multiply each coordinate by the scale factor

1/3 * 15 = 15/3 = 5

1/3 * 30 = 30/3 = 10

The point (15, 30) dilates to (5, 10)

This trick only works if the center of dilation is the origin.

answer

see attachment

explanation

the given function is

this function has y-intercept at

-4 and a slope of 2.

note that, the graph has a positive slope.

the graph that represents this function is the straight line that moves upward from left to right.

the graph touches the y-axis at -4.

the correct choice is the graph shown in the attachment.
