Question

What is the slope of the line represented by the equation -2y=x-1?

Answer 1

In the equation of a straight line:  y = mx + c, slope is  denoted

 by the letter m.

$\it -2y = x-1|_{:(-2)} \Rightarrow y = -\dfrac{1}{2}x+\dfrac{1}{2} \Rightarrow m = -\dfrac{1}{2}$

Answer 2

The slope is negative one half or -1/2
