Answer:
y= -3x -2
Step-by-step explanation:
(0 , -2) and a slope of -3
The -2 is the y-intercept, put the initial point there
Use that point and put the -3 slope 
 
        
             
        
        
        
Answer:
37
Step-by-step explanation:
all triangle's angle measures add up to 180
180-98-45 = x
x = 37
 
        
                    
             
        
        
        
The inequality that explains why the three segments cannot be used to construct a triangle is ED + EF < DF
<h3>Inequalities </h3>
From the question, we are to determine which of the given inequalities explains why the three segments cannot be used to construct a triangle 
From the given information, 
Line DE is about half the length of line DF 
That is, 
ED = 1/2 DF 
Also, 
Line FE is about one-third of the length of line DF
That is, 
EF = 1/3 DF 
Then, we can write that
ED + EF = 1/2DF + 1/3DF
ED + EF = 5/6 DF
Since, 
5/6 DF < DF 
Then, 
ED + EF < DF
Hence, the inequality that explains why the three segments cannot be used to construct a triangle is ED + EF < DF
