Step-by-step explanation:
The slope of the line that represents the relationship is 0.7692
<h3>slope of a line</h3>
The formula for calculating the slope of a line is expressed as;
Slope = y2-y1/x2-x1
Using the coordinate points (1.3, 1) and (2.6, 2)
Substitute
Slope = 2-1/2.6-1.3
Slope = 1/1.3
Slope = 0.7692
Hence the slope of the line that represents the relationship is 0.7692

I'm almost certain x = 1.25 might be wrong but I got it both times..
9 : 2 = 18 : 4
As: 9 x 2 : 2 x 2 = 18 : 4
--------------------
36 : 8 = 18 : 4
As: 18 x 2 : 4 x 2 = 36 : 8
--------------------
72 : 16 = 18 : 4
As: 18 x 4 : 4 x 4 = 72 : 16
