Point B has coordinate B(1, –1). What is the coordinate of B' under a scale factor of 3?
1,-1
3,-3
-2,2
-6,6

Answer:

The coordinate B' is \(B' = (3, -3)\).

Step-by-step explanation:

The new coordinate is computed by applying the scale factor with respect to origin:

\(B' = \alpha \cdot B\)

\(B' = 3\cdot (1,-1)\)

\(B' = (3\cdot 1, 3 \cdot (-1))\)

\(B' = (3, -3)\)

Answer:

B) 3,-3
