Answer:
?
Step-by-step explanation:
what is the question
 
        
             
        
        
        
The equation of the line is C. 1X/2 -2
How you figure this out is you first say when x is zero y is what?
y= 1/2 (0) - 2
You would then see that y=-2 (0,-2)
Plot that point
Next you need to find the slope of the line.
Remember slope is rise over run.
When you 'rise' up one (from -2) and 'run' 2
you are now at the point (2,-1) which is on the line. 
You can continue doing rise/run along the line to check your answer. 
I hope this makes sense! Let me know if you have any questions :)
        
             
        
        
        
Answer:
m∠3 = 73°
Step-by-step explanation:
Vertical angles are equivalent in measure. Complement angles add up to 90°, so subtract 17° from 90° to get your answer.
