Review of LT #12 and #13: I can graph and write linear equations

Front

What is the slope of parallel lines?

Back

The slopes of parallel lines are the same.

Front

How do you find the y-intercept of a linear equation?

Back

Set x = 0 in the equation and solve for y.

Front

How do you find the x-intercept of a linear equation?

Back

Set y = 0 in the equation and solve for x.

Front

Write the equation of a line in slope-intercept form with a slope of 3 and a y-intercept of 4.

Back

y = 3x + 4

Front

What is the slope of perpendicular lines?

Back

The slopes of perpendicular lines are opposite reciprocals.

Front

What is 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

If a line has a slope of 2, what is the slope of a line perpendicular to it?

Back

The slope of the perpendicular line is -1/2.

Front

What does the term 'slope' represent in a linear equation?

Back

The slope represents the rate of change of y with respect to x.

Front

How can you determine if two lines are parallel from their equations?

Back

If the slopes (m) of both lines are equal, the lines are parallel.

Front

How can you determine if two lines are perpendicular from their equations?

Back

If the product of their slopes is -1, the lines are perpendicular.
