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.
The line y = 6 is horizontal and has a slope of zero, as does any line that is parallel to it.
The same. Parallel lines have the same slope.
The slope is 5. Parallel lines always have the same slope.
if the slope of a line is 2/3, then the slope of a parallel line would be 2/3.
the slope is infinite because you have a vertical line. To find a parallel line, the formula would be "x= any number" because that would also give you a vertical line.
The parallel line would also have a slope of zero (both are horizontal lines).
Slope = zero. The line is horizontal, parallel to the x-axis.
The slope is rise over run. If another line was parallel, the slope would be the same.
Slope = -1
It will have the same slope which is 2
