Question

Two lines are graphed below. What can we conclude about them? Select all that apply.

coordinate plane showing y equals 3 x plus 1 and y equals negative one third x minus 2



The lines are perpendicular.


The lines are parallel.


The lines have the same slope.


The lines have opposite reciprocal slopes.

Answer 1

The lines are perpendicular.

Explanation:

If two lines are graphed on the coordinate plane showing y equals 3 x plus 1 and y equals negative one third x minus 2, we can conclude that the lines are perpendicular.

Slope = 3

Slope of second equation: -1/3

Therefore, thee slopes are perpendicular.

Answer 2

Hi there!

The answer to this question is: The lines are perpendicular.

Explanation:

If you take the slope of the first equation its 3. To find its perpendicular slope you take the negative reciprocal of it. You flip the number into a fraction and make it negative, this case you get -1/3 which is the slope of the second equation therefore they are perpendicular
