Ksenya-84 [330]
Use the Pythagorean theorem...
a²+b²=c², in this case a²=c²-b<span>²</span>

Which equation represents a line which is parallel to the line y = -7/2x-3
Maksim231197 [3]

You do not have the options listed, but I will tell you what the line needs:

[] A parallel line will need the same slope.

- The slope is our m in y = mx + b

[] What will this be for our problem:

- y=\frac{-7}{2}x-3

- Our slope is \frac{-7}{2}

[] So what will the line look like:

- y=\frac{-7}{2}x +?

- Since you do not have the options listed, I cannot tell you the answer, but I can tell you the answer will have a slope of \frac{-7}{2}

Have a nice day!

     I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)
