Adding 2 to the three gives you y=6x+5
Answer:
-1
Step-by-step explanation:
If a straight line passes through the known points (x1, y1) and (x2, y2), the its slope is given by 
Now, in our case the straight line passes through the points (1.8, - 3.4) and (6.8, - 8.4).
Therefore, the slope of the required straight line will be 
( Answer )
36 + 5 = 41
