12/8 Exam Review Day 2

Front

What is the slope of the line represented by the equation y = -5/3x + 2?

Back

-5/3

Front

What do the slopes of parallel lines have in common?

Back

The slopes of parallel lines are the same.

Front

What is the equation of the line of best fit if the data suggests a positive correlation?

Back

y = 6.3x + 62

Front

How can you determine if a graph represents a function?

Back

A graph represents a function if it passes the vertical line test.

Front

What is the relationship between the slopes of perpendicular lines?

Back

The slopes of perpendicular lines are negative reciprocals of each other.

Front

If two lines have the equations y = -2/3x + 2 and y = 3/2x + 9, what is their relationship?

Back

They are perpendicular.

Front

What is the formula to calculate the slope between two points (x1, y1) and (x2, y2)?

Back

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

Front

What does a slope of 0 indicate about a line?

Back

A slope of 0 indicates a horizontal line.

Front

What does an undefined slope indicate about a line?

Back

An undefined slope indicates a vertical line.

Front

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

Back

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