This question will find the equation to a perpendicular line to the equation, y equal 1 4th x minus 1.
00:13
As you can see on the whiteboard here, i have graphed right here, y equals 1 4th x minus 1, where when x is 0, it intersects the x -axis at negative 1.
00:26
The point given is negative 4, 5.
00:33
And it is located up here.
00:36
Now, to find a perpendicular line, it is the opposite reciprocal or the negative reciprocal of the slope.
00:44
Looking at this equation, the slope is 1 -4.
00:53
So, for our new perpendicular line equation, there are new slope...
