Ok so you multiply -3 on both sides so on the right it is -48 and then the left the -3 is cancelled out and so you are left with -6+c . You add 6 on both sides and so it is -42=c so c=-42
Answer: B
You can find slope by using the slope formula. Because we are already given two coordinate points, we can use that to find our slope. The slope formula is . This also refers to or 10/-4 or -5/2. Any coordinate with the x-value as 0 means that that coordinate is the y-intercept. Because (0,5) has 0 as its x-value, the y-intercept is 5.
I think it is B there is a weak negative association between the variables
40?
I’m not sure but I know u need 40 marks it depends on the amount of marks per q
Hope that helped somehow
