Answer:

Step-by-step explanation:
By using the midpoint formula and the equation of the line, the equation of the line of symmetry is x = - 2.
<h3>How to derive the equation of the axis of symmetry </h3>
In this question we know the locations of two points with the same y-value, which means that the axis of symmetry is parallel to the y-axis and that both points are equidistant. Thus, the axis of symmetry passes through the midpoint of the line segment whose ends are those points.
First, calculate the coordinates of the midpoint by the midpoint formula:
M(x, y) = 0.5 · (- 7, 11) + 0.5 · (3, 11)
M(x, y) = (- 2, 11)
Second, look for the first coordinate of the midpoint and derive the equation of the line associated with the axis of symmetry:
x = - 2
By using the midpoint formula and the equation of the line, the equation of the line of symmetry is x = - 2.

The figure is called an Acute Triangle. The Area is 199.96 centimeters squared. The perimeter (or circumference) is 68.
Answer:
Ella got the highest marks.
Step-by-step explanation:
Given that:
Camilla got 4/5 of the 200 marks.
Marks of Camilla = 
Marks of Camilla = 160 marks
Lincoln got 44% of the 200 marks.
Marks of Lincoln = 
Marks of Lincoln = 88 marks
Ella got 198 out of 200.
On comparing,
198 is the highest out of 200.
Hence,
Ella got the highest marks.
