Spiral Review 2

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they have the same slope and will never intersect.

Front

What does it mean for two lines to be perpendicular?

Back

Two lines are perpendicular if the product of their slopes is -1.

Front

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

Back

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

Front

How do you determine the slope from the equation y = mx + b?

Back

The slope is the coefficient of x, represented by m.

Front

What is the y-intercept in the equation y = 2x + 3?

Back

The y-intercept is 3, which is the value of y when x = 0.

Front

If a line has a slope of 3, what does this indicate about its steepness?

Back

A slope of 3 indicates that for every 1 unit increase in x, y increases by 3 units, making the line steep.

Front

What is the equation of a line that is parallel to y = 3x + 2 and passes through the point (3, -1)?

Back

Front

What does the equation x = 6 represent on a graph?

Back

The equation x = 6 represents a vertical line that crosses the x-axis at 6.

Front

How can you tell if two lines are neither parallel nor perpendicular?

Back

If the slopes of the two lines are different and their product is not -1, they are neither parallel nor perpendicular.

Front

What is the meaning of the inequality x ≥ 10 in the context of money?

Back

It means that Kristin should take at least $10 with her to the movie.
