The slope of the linear equation is 15, so the correct option is B.
<h3>
How to get the slope of the line?</h3>
A linear equation can be written as:
y = a*x + b
Where a is the slope and b is the intercept.
For a line that passes through the points (x₁, y₁) and (x₂, y₂), the slope can be written as:
Here we have the two points (0.2, 3) and (0.4, 6), so the slope is:
So the slope of the line is 15, which means that the correct option is B.
