Question

Draw the image of a triangle after a dilation with a scale factor of 2.

Answer 1

Let's begin by listing out the information given to us:

The vertices of the triangle is given as:

$(0,0),(0,5),(-4,2)$

Dilation by a scale factor of 2 means the triangle will be enlarged, the coordinate of the vertices become:

$\begin{gathered} (0,0)\rightarrow2(0,0)=(0,0) \\ (0,5)\rightarrow2(0,5)=(0,10) \\ (-4,2)\rightarrow2(-4,2)=(-8,4)_{} \end{gathered}$

We will then graph this
