Question

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

Answer 1

B. -1/2

Step-by-step explanation

The slope of a line from a graph can be found by dividing the rise by the run:

In this line the rise is 1 and the run is 2, but to the left, so it's negative. The slope of this line is:

`\text{slope}=\frac{\text{rise}}{\text{run}}=(1)/(-2)=-(1)/(2)`

But we want to know the slope of a parallel line to the given line. It is the same slope, because paralell lines have the same slope.
