Answer:
y = - 2
Step-by-step explanation:
The equation of a horizontal line parallel to the x- axis is
y = c
where c is the value of the y- coordinates the line passes through.
The points (2, - 2) and (0, - 2) have the same y- coordinate and therefore lie on a horizontal line with equation
y = - 2
What shape is it ? Area u just do 5X3 = 15cm2 and perimeter u add all the sides and find the missing sides
we know that
The<u> Triangle Inequality Theorem</u> states that the sum of any 
sides of a triangle must be greater than the measure of the third side
in this problem
we have the segments EF, FD and DE
<u>to construct a triangle three inequalities must be met</u>
<u>case 1) </u>
<u>case 2) </u>
<u>case 3) </u>
therefore
<u>the answer is</u>
ED + EF < DF
EF + FD < DE
