Step-by-step explanation:
the gradient of the line = 2 units/ 3 units = 2/3
 
        
             
        
        
        
none of the above, -90 and 270 are the same position on the unit circle
 
        
             
        
        
        
Answer:
X=15
Step-by-step explanation:
Ignore the increase for equasion. This is factored in but irellevent. Orignal x value is 13, but increases to 15, and orignal x value is not needed for this equasion. (its there to confuse you) 
L+L+W+W=66.
(w+3) +(w+3) +w +w = 66
(4xw) + 3 +3= 66
4 x w = 66 -3 -3
4 x w =60 
60/4= 15.
L= 15+ 3 =18
W = 15.
W + W + L + L 
15 + 15 + 18 +18 =66
 
        
             
        
        
        
Answer:
your y intercept is 90 and the equation would be y= 90 and x is unknown
