Step-by-step explanation:
it would at LEAST be like around 20-30 because a 0 can drop something FAST
 
        
             
        
        
        
The slope is the factor in front of x, so slope is 9.
The y intercept is 7 (that's the point of cross the y axis, where x=0)
There are multiple definitions of "standard form" for lines, so here are the two i can think of:
9x - y = -7    (the implicit function form)
or 
y-7 = 9*(x-0)  (the point-slope form)

Using scientific notation, it is found that:
67 ns =  s
s
<h3>What is scientific notation?</h3>
A number in scientific notation is given by:

With the base being  .
.
In this problem, the amount is of 67 ns.
Each ns has  seconds, hence:
 seconds, hence:

We want the base between 1 and 10(exclusive), hence, we move the decimal digit one digit to the left and add one to the exponent, and the representation is:
67 ns =  s
s

The line starts at the origin and goes down by two.
