Front

What is the y-intercept?

Back

The y-intercept is the point where a line crosses the y-axis. It is represented by the value of y when x = 0.

Front

What type of slope does a line with a downward trend have?

Back

Negative slope.

Front

What is an example of a dilation rule in transformations?

Back

(2x, 2y) is an example of a dilation rule, indicating that the figure is stretched by a factor of 2.

Front

In the equation y = mx + b, what does 'm' represent?

Back

The slope of the line.

Front

What are the 3 clue words that imply where to put the 'x' in an equation?

Back

per, every, each.

Front

What is the definition of slope?

Back

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

Front

How do you calculate the slope between two points (x1, y1) and (x2, y2)?

Back

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

Front

What does a zero slope indicate about a line?

Back

A zero slope indicates that the line is horizontal.

Front

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

Back

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

Front

What does an undefined slope indicate about a line?

Back

An undefined slope indicates that the line is vertical.
