I think the attached photo supports for your question
Here is my anser:
We need to find the slope of the of and from the graph, we see that if x increases from 2 to 4, y decreases from 4 to -2. Thus, the slope of the blue line is : = -3
But the slope of the perpend. bisector of the blue line is the negative reciprocal of -3, or m= 1/3.
Let's find the slope-intercept form of this bisector. We need to determine b in y=mx+b. Referring to the midpoint of the blue line, x= 3; y= 1; and m=1/3. Then
y=mx+b becomes 1=(1/3)(3) + b. Solving for b: 1=1+b. Then b=0.
Thus, the equation of the perpendicular bisector of the blue line through (3,1) is y=mx + b, or y=(1/3)x + 0, or y=x/3.

Answer:
The quantity of Jennie's skin cell were not burned is 119.601 × .
Step-by-step explanation:
Given as :
The percentage of Jennie's skin cell were burned = 3 %
The quantity of Jennie's skin cell were burned = 3.7 ×
Let The quantity of Jennie's skin cell were not burned = x
Let Total quantity of whole skin cell = n
<u>Now, According to question</u>
The quantity of Jennie's skin cell were burned = Total quantity of whole skin cell × percentage of Jennie's skin cell were burned
i.e 3.7 × = n × 3 %
Or, 3.7 × = n ×
Or, n = 3.7 × ×
Or, n =
i.e n = 1.233 ×
Or, Total quantity of whole skin cell = n = 1.233 ×
<u>Now, Again</u>
∵ percentage of Jennie's skin cell were burned = 3 %
So, percentage of Jennie's skin cell were not burned = 100 % - 3 % = 97 %
so , The quantity of Jennie's skin cell were not burned = 97 % of Total quantity of whole skin cell
Or, x = × n
Or, x = × 1.233 ×
∴ x = 119.601 ×
So, The quantity of Jennie's skin cell were not burned = x = 119.601 ×
Hence, The quantity of Jennie's skin cell were not burned is 119.601 × . Answer
