What is the slip of a line that is perpendicular to the line represented by the equation y - 5x = 5?

-1/5

Step-by-step explanation:

First find the slope of the line

y- 5x=5

Add 5x to each side

y = 5x+5

This is in slope intercept form

The slope is 5 and the y intercept is 5

We want a line that is perpendicular

The slope is the negative reciprocal

-1/ (5)

 = -1/5

The slope of the line that is perpendicular is -1/5

Answer : (A) They all indicate a constant speed.  

Explanation :

In this case, four line graphs represent speed in m/s. The x-axis is labeled in seconds (time) and the y-axis is labeled in meters (distance).

The slope of the distance-time graph gives the slope. It can be seen from the attached figure that, in each case, the speed is constant everywhere.  

Hence, the correct option is (A) " They all indicate a constant speed ".
