Roughly 5%
Step-by-step explanation:
.05*34.75=1.74
34.75-1.74=33.01
-2x+3
Using y=mx+b
To make the line perpendicular, you just need to make the slope (m=2) negative. To make it go through (-1, 5), you just need to adjust the b value to raise the graph to a point where it will pass through the point.
