Question

If slope of line 1 is -1/2 and is parallel to line 2 what's the slope of line 2

Answer 1

for two lines to be parallel, the lines have to have equal slopes. Line 2 should have the same exact slope as line 1.
if it was perpendicular then the line would have the reciprocal (for example: Line one has the slope of 3, then line two would have the slope of 1/3; get it?)

Answer 2

the slope of line 2 is
`(-1)/(2)`

Explanation:

If two lines are parallel then their slope are also equal
`m_1 =m_2`

we have given with slope of line 1 is
`m_1 =(-1)/(2)` and we need to find the slope of line 2,

so,

`m_1 =m_2`

`(-1)/(2) =m_2`

⇒
`m_2=(-1)/(2)`

Therefore, the slope of line 2 is
`(-1)/(2)`
