If A = (x1, y1) and B = (x2, y2)
then, if
x1 ≠x2 the slope of AB is (y2 - y1)/(x2 - x1)
There are various ways of interpreting slope > 0.
One way is that it implies that
y2 > y1 and x2 > x1
or
y2 < y1 and x2 < x1
that is both the coordinates of one point are greater than both the coordinates of the other point.
Note that if
x1 = x2 then the slope is not defined.
Yes, it is true; slope zero is no slope.
No.Unless the slope is zero, every line will extend from minus infinity to plus infinity. So part of it will be negative and part positive.No.Unless the slope is zero, every line will extend from minus infinity to plus infinity.

True.
The line has a slope of -4
it is a negative slope.
TRUE
Your statement is correct. y=mx+b when m is the slope and b is the y-intercept.
Perpendicular lines have slopes whose product is -1. As this is always true, if we think of .33 as about 1/3, then the perpendicular line would have a slope of -1/(1/3) which is -3.
No. This is true for any curved line, not just in economics.
True
It bisects the line segment at midpoint at 90 degrees and its slope is the reciprocal of the line segment's slope plus or minus.
