Writing Equations of Parallel Lines Practice

Front

What is the slope of a line parallel to the line whose equation is: -2x + y = - 7?

Back

The slope is 2.

Front

Which of the following lines is PARALLEL to the graph of 5x + 2y = 8?

Back

The line -10x - 4y = 7 is parallel.

Front

What is the point-slope form of equation of the line that is PARALLEL to y = -2x - 6 and passes through the point (-3, 11)?

Back

y - 11 = -2 (x + 3) is the point-slope form.

Front

Write an equation of a line that passes through the point (-2,3) and is parallel to the line x = 4.

Back

The equation is x = -2.

Front

Write an equation of a line that passes through the point (2,6) and is parallel to the line y = -3.

Back

The equation is y = 6.

Front

What does it mean for two lines to be parallel?

Back

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

Front

How do you find the slope of a line from its equation in standard form?

Back

Convert the equation to slope-intercept form (y = mx + b) to identify the slope (m).

Front

What is the slope-intercept form of a line?

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 3, what is the slope of a line parallel to it?

Back

The slope of a parallel line is also 3.

Front

What is the equation of a line parallel to y = 4x + 1 that passes through the point (0, 2)?

Back

The equation is y = 4x + 2.
