Neither.

Parallel lines have the same slope.
Perpendicular lines have negative reciprocal slopes.

Rewriting the 2nd equation to solve for y,
You get:

Y=1/5x + 1/2

The first equation slope is negative, and the second is positive. However, the second slope is 1/5, and not 5/1 - which would be the negative reciprocal of (-1/5)from the first equation.

Hope that helps!

The graph represents one side of the roof of a building. <br><br> The slope of the line is
Aliun [14]

Answer:

7/2, 3.5 (depending on which form you want it in)

Step-by-step explanation:

Looking at the numbers on the side, lets take two points they already gave us.

It goes up 14, and over 4 from 0,0.

14/4 Simplify.

7/2

7/2 is your slope

Note:

For those asking why it isn't "10/3" or anything else, It's because we can't be sure the line crosses that coordinate at that point. So lets just take two points where we know the actual coordinates, and derive the slope from that because it's more accurate.
