Answer:
C
Step-by-step explanation:
We want a line of best fit, which means we want to create a line that the data points will lie closest to.
One thing we can do is find the slope between the bottom-leftmost point and the top-rightmost point. This is because if we were to draw a line connecting these two, it will cut through the data quite well.
Those two points are (9, 15) and (16, 18), so the slope is change in y divided by the change in x:
(18 - 15) ÷ (16 - 9) = 3 ÷ 7 ≈ 0.4
Eliminate A and B.
Now we need to determine the y-intercept. This needs no calculations; simply look at the graph: there's no way a line cutting through the y-intercept point of (0, 18) will perfectly match the data points; instead it must be a y-intercept lower than 18. So, eliminate D.
The answer is C.
Answer:
0.1,0.5,0.8,0.9
Step-by-step explanation:
Answer:
Positive
Step-by-step explanation:
-7+28=21
21 is positive
Answer:
-2
Step-by-step explanation:
to find the slope from to points you can follow this equation
m=y2-y1 / x2-x1
so plug in the points
1-3/ 1-0
-2/1
-2
