Answer:
C'(4,4)
Step-by-step explanation:
The dilation of quadrilateral ABCD over the origin by a scale factor of 2 has the rule
(x,y)→(2x,2y)
So,
- A(-3,-1)→A'(-6,-2)
- B(-1,1)→B'(-2,2)
- C(2,2)→C'(4,4)
- D(3,-2)→D'(6,-4)
Hence, the coordinates of the image point C' are (4,4) (see attached diagram for details)
Answer:
Step-by-step explanation:
We can write the equation using the point and the slope .
Formula we need to use is the point slope formula
Which is given by
Y-y1= m(X-x1)
Here given that (x1,y1)=(1,-1) and m = -3
x1= 1
y1 = -1
so equation is
Y-(-1) = -3 (x-1)
Distribute the slope
y+1 = -3x+3
y= -3x+3-1
y = -3x + 2
So the equation is
y =-3x +2
