The equation of the line will be y = -3.9, and the height after rounding off will be -4.
<h3>What is a straight line?</h3>
A straight line is a combination of endless points joined on both sides of the point.
The slope 'm' of any straight line is given by:

The horizontal line can be defined as:
y = a
Where a is the constant.
Here a = -3.9
y = -3.9
The height = -3.9 ≈ -4
Thus, the equation of the line will be y = -3.9, and the height after rounding off will be -4.

Answer: number 5 is A number 6 is B
Step-by-step explanation:
Surface area of cube = 6s²
<span>6s² = 3750
</span>
<span>s² = 3750 / 6
</span>
<span>s² = 625
</span>
s = √625
s = 25
length of one side = 25 feet.
