Answer:
It could be a) -3
Step-by-step explanation:
I'm not quite sure but it may be.
Answer:
Step-by-step explanation:
y = (5/4)x + (5/4)
Slope = 5/4
Parllel lines have same slope
Slope of the line parallel to this line = 5/4
(-2 , 3)
y -y1 = m(x -x1)
y - 3 = (5/4)(x - [-2])
Answer:
Extrapolation
Step-by-step explanation:
Given the data:
Distance (mi): 2 2.5 3 3.5 4
Time (min): 23 28 34 34 40
Line of best fit for the data:
y = 8x + 8
Making use of the best fit equation to make prediction of time is an example of extrapolation. This is because our result will be based in the fact that further prediction of the time it takes for any predicted distance will follow the same trend. Hence, it is important to note that a best fit line or regression model uses extrapolation techniques to make predictions.
Hence,
For the above ; estimate for X =5 will be ;
y = 8(5) + 8
y = 40 + 8
y = 48 minutes
20.25-9(1/2)+11
=20.25-4.5+11
=26.75
My calculator shows this number as 1.45E14
