Effects of Transformations on Linear Equations

Miss Smith explains various transformations of linear equations, including dilation through and not through the origin, reflections over the x and y axes, and vertical shifts. Each transformation is demonstrated with examples and visual aids, highlighting changes in slope and y-intercept. The video concludes with a practice exercise for viewers.

What is the main focus of the video tutorial?

• Transforming quadratic equations

• Transforming linear equations

• Graphing quadratic equations

What happens to the slope and y-intercept during a dilation through the origin?

• Both change

• Only the slope changes

• Only the y-intercept changes

• Neither changes

If a line is dilated through the origin by a factor of 3, what happens to the line?

• It remains unchanged

• It shifts upwards

• It becomes steeper

• It shifts downwards

What is the main characteristic of a dilation through the origin?

• The slope changes
