The 3 one or second make the most sense
Given:
Two points that are close to the line of best fit are (2,70) and (4.5, 90).
To find:
Th equation of best fit line using the given two points.
Solution:
We know that, if a line passes through the two points, then the equation of line is

Two points (2,70) and (4.5, 90) are close to the best fit line.
Consider the two points (2,70) and (4.5, 90). So, the equation of line is




Adding 70 on both sides, we get


Therefore, the equation of best fit line is
.
All you have to do is 4 to the power of -3 and what that answer is you get y. You will do the same for 3. You will do 4 to the power of 3 which comes out to be 4*4*4.
5(2x-3)=60
2x-3=12
2x=12+3
2x=15
x=15/2
