A straight line cannot have two slopes. A curve, however, might have a different slope at every different point.
can a line have two slopes
Positive 3
one is the negative reciprocal of the other; that is if the slope of one line is 2, the other is -1/2
In geometric terms, a line can have only one slope. if there is more than one slope, it is not a line, it is multiple lines or a second (or higher) order graphical representation of a function in two dimensional space.

can a line have two slopes
If two lines are parallel, they have the same slope.(And if they are perpendicular, the product of their slopes is minus one - unless one line is horizontal and the other vertical.)
Positive 3
Yes it can, but it would not then be a straight line but an angle.
If the gable is formed by the two slopes and a horizontal line, it is called a gable roof.
Their slopes are equal.
their slopes are negative reciprocals.
one is the negative reciprocal of the other; that is if the slope of one line is 2, the other is -1/2
Slopes of perpendicular lines will be opposite reciprocals. This means that the slopes have opposite signs and that one is 1/ the other. For example, 2 and -1/2.
In geometric terms, a line can have only one slope. if there is more than one slope, it is not a line, it is multiple lines or a second (or higher) order graphical representation of a function in two dimensional space.
A line that slopes to the right and up has a positive slope.
