Jamestown- Why are there positive and negative interactions when cultures meet?
Reflection across the line, y=-x or x=-y
basically, for every x, switch it for y and times -1
for every y switch it for x and tiimes -1
in short, switch the x and y and times both by -1
vertex is(1,-3)
switch
(-3,1)
times -1 to both
(3,-1)
2nd one is answer
Answer:

Step-by-step explanation:
A dilation is an enlargement or reduction of an object by a scale factor and with a center of dilation. The scale factor refers to the change in size. The center of dilation is a point about which we are dilating an object.
The dilation with the center of dilation at the origin and a scale factor of k has the rule

This means that the image of the point with coordinates (x,y) after the dilation by a scale factor of k with center of dilation at origin will have coordinates (kx,ky).
Its 1 if thats what your asking :P
