Two parallel lines have equal slopes.

The same slope

No, only lines that have the same slope can be parallel.

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.)

No. In order to be parallel, two lines would have to have the same slope, and different intercepts.Why? Two lines with different slopes, but the same intercepts would result in two intersecting lines. Two lines with the same slope, and the same intercept would result in the same line. Two lines with the same slope, and different intercepts would be parallel.

If two lines are parallel and one has a slope of 1.3, what is the slope of the other line?

The slope is rise over run. If another line was parallel, the slope would be the same.

If they are parallel then the slope of the other line is also 7

If two lines are parallel, then they will both have the same slope.

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 slope of any parallel lines is always the same. Parallel means they are co-planar which means lie in the same plane, and never intersect. In order for the lines to not intersect you would need the same slope. In this case the answer is -2/3.

Parallel lines have the same slope.

No but if the two lines are parallel then they will have the same slope.

Two parallel lines have equal slopes.

The same slope

yes they can be parallel because for a pair of lines to be parallel the slope must be the same no matter if the slope is positive or negative.
