Yes, (3, 2) is a solution to y = 2x - 4. (:
Step-by-step answer:
Given an enlargement from preimage (ABC) to image (A'B'C').
Need to find scale factor.
Solution:
Scale factor = linear size of image / linear size of preimage.
From the accompanying diagram, we see that
L(preimage) = AC = 4 units
L(image) = A'C' = 12 units
Therefore
Scale factor = L(image) / L(preimage) = 12 / 4 = 3
The easiest way to find the area of a triangle is by doing 1/2 base x height. So halve the base, 2.4 / 2 = 1.2. Now do 1.2 x 0.8. Which equals 0.96.
