Answer:
   y-intercept: (0, 5); slope: 1/4
Step-by-step explanation:
The slope (m) is found from ...
   m = (y2 -y1)/(x2 -x1)
Using the first two points in the table, this is ...
   m = (8 -6)/(12 -4) = 2/8 = 1/4 . . . . . eliminates choices A and C
__
Then, the point-slope form of the equation of the line can be written as ...
   y -y1 = m(x -x1)
   y -6 = (1/4)(x -4) . . . fill in known values
   y = 1/4x -1 +6 . . . . . add 6
   y = 1/4x +5
Then the value of y when x=0 is ...
   y = 0 +5 = 5
So, the y-intercept is (0, 5) and the slope is 1/4, matching the last choice.
 
        
             
        
        
        
Answer:
x = 11.4
Step-by-step explanation:
14.12 =  ( 3.6x - 12.8 )
 ( 3.6x - 12.8 )
Rewrite so that the equation is entirely in decimals;
14.12 = 0.5( 3.6x - 12.8 )
Distribute;
14.12 = 1.8x - 6.4
Inverse operations;
14.12 = 1.8x - 6.4
+6.4            +6.4
20.52 = 1.8x
/1.8        /1.8
11.4 = x
