A front yard is drawn on a coordinate grid, as shown. The line represents the façade of a house. The owner wants to build a fence that is perpendicular to the house and runs through (6, 5).
Which line represents the fence?

no problem

Ok so what is the slope of the current line?
OpenStudy (anonymous):
i dont know
OpenStudy (anonymous):
Well what is slope? Rise/Run right?
So count how many the line goes down in a run of 1
OpenStudy (anonymous):
3?

-3
Because it is going down right?
OpenStudy (anonymous):

Umm as the answer or as the equation of the line?
BEcause that isn't correct for either
OpenStudy (anonymous):
Just look at the slope of that line for now k?
-3
OpenStudy (anonymous):
Now it is a fact in math that if you want a line to be perpendicular there has to be another line with an OPPOSITE SIGN and it has to be an INVERSE
OpenStudy (anonymous):
So for example if I want a line to be perpendicular to a line with a slope of 2 it needs to have a slope of -1/2
OpenStudy (anonymous):
Do you understand?
