Not always because it can also be negative
No.
If the slope (line)is in upward direction, it is called positive slope
Never.
You must find the slope, if it is positive, then the line is always increasing. If it is negative, then the line is always decreasing.
For two lines to be parallel they must have the same slope. A line parallel to a line with slope -2 would have a slope of -2.
No because the slope of a line can be positive or negative
The correct properties are found in answer A. The slope of a line is always positive, no matter which way the line is angled or heading.
No.
The slope is always positive A negative slope will always pass through quadrant II and IV
If the slope (line)is in upward direction, it is called positive slope
Never.
a line with a positive slope rises from left to right
The slope was always there
positive
Rise of a line is a positive slope.
A perpendicular lines slope is always the negative or opposite reciprocal of a lines slope. Therefore, if your slope is -13/1 then the perpendicularity of the other line is 1/13. The 13 would change positive there fore its its already a negative number then change it posiive.
You must find the slope, if it is positive, then the line is always increasing. If it is negative, then the line is always decreasing.
