Multiplying Coordinates by Scale Factor

The video tutorial explains how to dilate a triangle using a scale factor of 3/4. It highlights the challenge of multiplying by a fraction and demonstrates the process of reducing the size of triangle XYZ. The tutorial focuses on multiplying each coordinate by the scale factor, replacing original coordinates with new values, and graphing the results to confirm the reduction. The video emphasizes understanding the impact of a scale factor less than 1 and provides step-by-step instructions for calculating and graphing the new coordinates.

What is the effect of using a scale factor less than 1 in dilation?

• The shape disappears.

• The shape becomes smaller.

• The shape remains the same size.

• The shape becomes larger.

Why is it challenging to multiply by the scale factor 3/4?

• Because it is a decimal.

• Because it is a whole number.
