In which step did Ryan make the first error?

C ( step 3 )

Step-by-step explanation:

Ryan wants to describe the translation shown on the grid below.

On a coordinate plane, triangle X Y Z is shifted 1 unit to the left and 3 units up to form triangle X prime Y prime Z prime.

Ryan uses the following steps to describe the translation.

Step 1Identify the pre-image and the image:

The pre-image is triangle XYZ, and the image is X prime Y prime Z prime.

Step 2

Identify the number of units that each point moves horizontally:

Each point moves one unit left.

Step 3

Identify the number of units that each point moves vertically:

Each point moves three units down.

Step 4

The translation is one unit left and three units down.

In which step did Ryan make the first error?

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
