Question

The slope of a line is -1/2 . What is the slope of a line that is parallel to it? A. 1/2 B.2 C. -1/2 D. -2

Answer 1

Explanation:

We know any line that is parallel to other line has same slope.

Here, m1=m2

So, slope will be -1/2.

Answer 2

For this case we have by definition, that if two lines are parallel then their slopes are equal. That is to say:

`m_ {1} = m_ {2}`

If we have a line of the form:

`y_ {1} = - \frac {1} {2} x_ {1} + b_ {1}`

Then a parallel line will be given by:

`y_ {2} = - \frac {1} {2} x_ {2} + b_ {2}`

That is, the slopes are the same!
