Answer:
342
Step-by-step explanation:
just add the 128 and 107 which will give u 235 and multipy that by 2 which will give u 342
You divide the difference of the y-coordinates of 2points on a line by the difference of the x-coordinates of the same 2points
Find the change between the first two sets:
12-9 = 3
14.4 - 10.8 = 3.6
3.6/3 = 1.2
Now find the change between the last two sets:
12 - -3 = 15
14.4 - 3.6 = 10.8
10.8/15 = 0.72
1.2 does not equal 0.72 so the answer is No
