Step-by-step explanation:
The survey is said to be biased by non-response survey if many people did not respond to the survey this might be much affected the result of survey.

Also these peoples has different opinion from other peoples who respond in the survey. Thus this cause biased.
So the equation is parallel and the slope will be 2 y=0.6x+b sub in(-2,2) for x and y to find b 2=0.6(-2)+b 2+1.2=b b=3.2 therefore the equation is y=0.6x+3.2
