Day 1: Answers
Question 1:
The answer is y = 2x+10 because you need to set 2x-y equal to 10. So subtract y from each side which leaves you with 2x=10+y. Once this is done you subtract 10 from both sides which leaves you with 2x-10=y. Y now equals 2x-10Question 2:
The answer to A is 2/1. Because 26-14 equals 12 and 12-6 equals 6. So change in Y over change in X would be 12/6 and reduced it is 2/1. The answer to B is -1/3 because 6-10 equals -4 and 15-3 equals 12 and that's -4/12 but reduced it is -1/3.Question 3:
This is the line of best fit. It is going straight through two points that connect with the line. There are an even amount of points one each side of the line and thats the reason WHY it is the line of best fit.
