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:
C. 2
Step-by-step explanation:

Subtract inside the parenthesis inside the numerator.

Multiply -8 and 5 in the numerator.

Rewrite the denominator knowing that x - (-y) = x + y.

Add inside the parenthesis in the denominator.

Multiply -2 and 10 in the denominator.

Rewrite the fraction knowing that (-x)/(-y) = x/y.

Divide 40 by 20 to get: 2.
The answer is 44.3 I know because that 9 goes ^
