Question

The lines graphed below are perpendicular. The slope of the red line is 4.

What is the slope of the green line?

Answer 1

b. -1/4 you can see two points (0,2) and (4,1) you can do rise over run or y2-y1/x2-x1 2-1/0-4= -1/4

Answer 2

Answer: -1/4

Explanation:

so lets just eliminate some of the choices here.

4 and -4 are 4/1 or -4/-1 and it doesnt go up or down 4 here so those can be ruled out. If we look at which way the green line is facing, positive goes up on the graph, but green line is going down so we can rule out 1/4. So all that is left is -1/4, so there's your slope.
