The lines with a slope of 0 are horizontal lines because all the points on the line have the same y-coordinate on a graph. Using the slope formula on the line will give you 0.
5 + (-3) - 6
------------------------
Let's do the first part
5 + (-3) whenever you see a problem where you add a negative number just think of it as subtracting
5 - 3 = 2
-------------------------------------------
2 - 6 = -4
-4 is your answer
The slope of the line
is
.
The line perpendicular to the above line has slope
Its equation is
. Since this line passes through,
,

Thus the equation of the line in slope intercept form is
