The attached image represents the triangle after it has been enlarged
<h3>How to enlarge the triangle?</h3>
The given parameters are:
- Scale factor, k = -1/3
- Center, (a,b) = (-1,2)
From the graph, the coordinates of the triangle are:
A = (-4,2)
B = (-4,-4)
C = (-1,-4)
The rule of dilation is calculated using:

So, we have:

A' = (0, 2)

B' = (0, 4)

C' = (-1, 4)

Step-by-step explanation:
<h2>Answer 1 :</h2>

<h2>Answer 2 :</h2>

Use proportions because we know that the triangles are similar.

Cross multiply.
