Question

The graph of the line has an equation of y = 3x + 4. What is the equation of the line after a dilation with a scale factor of 1 2 , centered at the origin.

Answer 1

1) scale factor: 1 / 2

2) equation after scale dilation

y * (1/2) = (3x + 4) * (1 / 2)

y = 3x / 2 + 4 / 2

y = 3x / 2  + 2

Answer: y = 3x / 2 + 2
