Unit 2 Review - Dilations and Slope

Front

What is the equation of the line with a slope of -3 and a y-intercept of -3?

Back

y = -3x - 3

Front

What does Dilation mean in geometry?

Back

Dilation means to enlarge or reduce an object.

Front

What is the y-intercept in the equation y = -2x + 5?

Back

5

Front

How do you find the slope of a line given two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1)

Front

Does the image show a Dilation?

Back

Yes

Front

What is the slope of the line represented by the equation y = (3/2)x + 1?

Back

3/2

Front

What is the definition of a slope in a linear equation?

Back

The slope is the measure of the steepness of a line, calculated as the rise over run.

Front

If a line has a slope of -1/3, what does this indicate about its direction?

Back

The line descends from left to right.

Front

What is the formula for the slope-intercept form of a line?

Back

y = mx + b, where m is the slope and b is the y-intercept.

Front

What happens to a shape during a dilation with a scale factor greater than 1?

Back

The shape enlarges.
