Answer:
The x represents the value of the point on the x axis or the horizontal line, and the y represents the vertical line. Now, lets solve for the first point. We can first see that it only moves to the left by two from zero, which is basically -2. So, right now we have (-2,y). We then look for the y in which we see that it is down -6 from zero, so it will be (-2,-6). Time to look for the second point. We should get (2,-3). Now, with these two points, it is time to find the slope intercept form.

Answer:
196: 9.8
20: 1
x= 9.8 meters in 1 second 
Step-by-step explanation:
This can be determined by following writing equal ratios that represent a word problem. Then, the denominator must be divided from the numerator to get the unit rate/ meters per second. 
 
        
                    
             
        
        
        
Answer:
x = 2 and y = 3
Step-by-step explanation:
We have
 x+2y = 8 -----equation (i)
 2x-y = 1 -----equation (ii)
Now,
 x+2y = 8
or, x = 8-2y ------equation (iii)
Again,
 2x-y = 1
or, 2x = 1+y
or, 2x-1 = y
 Putting the value of 'x' from equation (iii)
or, 2(8-2y)-1 = y
or, 16-4y-1 = y
or, 16-1 = y+4y
or, 15 = 5y
or, y = 15/5
or, y = 3
Putting the value of 'y' in equation (iii)
 x = 8-2y
or, x = 8-(2×3)
or, x = 8-6
or, x = 2
Therefore, x = 2 and y = 3.
