When dealing with parallel lines in geometry, one fundamental rule is that parallel lines share the same slope. This means that if you have a line, let’s call it line k, with a given slope, any line that is parallel to it will have the exact same slope.
In this case, we know that line k has a slope of 23. Therefore, since line m is parallel to line k, it will also have a slope of 23.
To summarize, the slope of line m is 23, because parallel lines do not intersect and have identical slopes.
