A triangle has vertices A(0,0), B(8,0), C(3,-2). Find the coordinates of the triangle after a dilation with a scale factor of 4. The dilation is (X,Y) --- (4x,4y)
A(3,3), B(4,4), C(-3,-4)
A(-4,8), B(6.5,8), C(7,7)
A(0,0), B(32,0), C(12,-8)
State the coordinate of the image of the given point B (-10,-6) under a dilation with center at the origin with the given scale factor k = 1/2.
