They’re both related to science
The school conducted a survey To find out what ?
2) Intercepts are formed when the graph of the f(X) cuts the X or Y axis i.e. Y=0 or X=0 respectively.
b) (I) y=3x-2( putting X=0)
(0,-2)
(II) y=3x-2 (putting Y=0)
(2/3, 0)
c) (I)y= 3* 0.3-2= -1.1
(II) y=3*0.7-2= 0.1
Different populations will have different viewpoints on the boundaries (most likely bad viewpoints)
