To be honest i need more data but i think its 173m and 17300cm
Xy = k
4x = 7

x = 7/4
Answer:
B: 3
Step-by-step explanation:
For the line to be parrallel to the x-axis, it means the slope is zero.
Thus;
(y2 - y1)/(x2 - x1) = 0
(4k - 5 - (2k + 1))/(8 - 3) = 0
4k - 5 - 2k - 1 = 0
2k - 6 = 0
2k = 6
k = 6/2
k = 3
