Example Question #1 : How To Find A Line On A Coordinate Plane

Vt_custom_xy_xylinesegment1

Which equation of a line is parallel to line segment ?  

Possible Answers:

Correct answer:

Explanation:

In order for the equation to represent a line that is parallel to the line that is shown, the equation must have the same slope as line segment 

Since, line segment  has a slope of , the correct equation is: 

Example Question #2 : How To Find A Line On A Coordinate Plane

Vt_custom_xy_xysegment_3

The points in the above line segment are apart of which of the following linear equations? 

Possible Answers:

Correct answer:

Explanation:

The above line segment is a horizontal line that passes through the  axis at  Since this line is horizontal, it does not have a slope. Therefore,  is the correct answer. 

Example Question #3 : How To Find A Line On A Coordinate Plane

Vt_custom_xy_xysegment_3

Which of the following linear equations is perpendicular to the line segment shown above? 

Possible Answers:

Correct answer:

Explanation:

Since the line segment is horizontal, the equation that is perpendicular to the segment must run vertically. The only linear equation that runs vertically (perpendicular to ) is .

Example Question #4 : How To Find A Line On A Coordinate Plane

Vt_custom_xy_xysegment_3

At what coordinate point does the line  intersect with the line segment shown above? 

Possible Answers:

Correct answer:

Explanation:

Since,  is perpendicular to  the points must cross at , because it is the only coordinate point that both lines pass through. 

Example Question #5 : How To Find A Line On A Coordinate Plane

Vt_custom_xy_xyline5

At which coordinate point does this line segment cross the -axis? 

Possible Answers:

Correct answer:

Explanation:

Keep in mind that the values in the coordinate points are , thus the point  is the point at which the line segment passes through the  axis.
