Congruent = same shape & same size

Similar = same shape BUT sides are proportional. They may or may not be same size.

Translation = simply moving a shape from one spot to another, like sliding it to a different position.

Rotation = Turning or twisting.

Reflection = mirror image.

Dilation = Changes the size of an object.

• a translation 3 units to the left.

• a dilation by a factor of 3

• a reflection across the x axis

• a rotation of 180 degrees

All 8th grade students at a school answered Yes or No to the two survey questions:

Have you ridden on a city bus in the last year?

Have you taken a taxi in the last year?

The scatter plot shows the relationship between the number of oil changes a car has per year and the average engine repair costs in a year for a sample population.

The y-intercept of the estimated line of best fit is at the point ( 0, b ). Enter the approximate value of b.

Remember: y-intercept is where the line crosses the y axis.
