Front

What is the equation of a line with a slope of 2 and a y-intercept of 4?

Back

y = 2x + 4

Front

If a pizza has 8 slices and costs $12, how much does each slice cost?

Back

$1.50

Front

What can be concluded about two similar quadrilaterals?

Back

The corresponding angles are congruent.

Front

If the missing side measurement is 5.2, what is the total length of the sides if the other sides are 6.6, 8, and 4?

Back

Total length = 6.6 + 5.2 + 8 + 4 = 23.8

Front

What proportion can be used to find y if triangle ABC is similar to triangle DEF?

Back

Front

Define similar figures in geometry.

Back

Similar figures have the same shape but may differ in size; corresponding angles are equal and corresponding sides are proportional.

Front

What is the formula for finding the slope of a line given two points (x1, y1) and (x2, y2)?

Back

Front

What does it mean for two angles to be congruent?

Back

Two angles are congruent if they have the same measure.

Front

How do you calculate the cost per item?

Back

Cost per item = Total cost / Number of items.

Front

What is the relationship between the sides of similar triangles?

Back

The ratios of the lengths of corresponding sides are equal.
