How to find out if lines are parallel - Math

Two lines are parallel if they have the same slope. When a line is in standard form, the is the slope.

For the given line , the slope will be . Only one other line has a slope of :

By definition, two lines are parallel if they have the same slope. Notice that since we are given the lines in the format, and our slope is given by , it is clear that the slopes are not the same in this case, and thus the lines are not parallel.

Parallel lines have the same slope. In slope-intercept form, , is the slope.

Here the slope is ; thus, any line that is parallel to the line in question will also have a slope of .

Only one answer choice satisfies this requirement:

Note: the answer choice is incorrect. If put into form, the equation becomes . Therefore the slope is actually , not .

Two lines that are parallel have the same slope. The slope of is , so we want another line with a slope of . The only other line with a slope of is .
