Answer:

Step-by-step explanation:
The equation for a line is y=mx + b where m represents the slope
If a line is perpendicular to another line, it's slope is the negative reciprocal of the other line's slope.
The reciprocal of -4 is 
And the negative of that would be 
One million = 1,000,000
So Three million is 3,000,000
One thousandths is 0.001
So nine thousandths is 0.009
So three million and nine thousandths is 3,000,000.009
