Answer:
-1/2
Step-by-step explanation:
The slope of a line is given by
m = (y2-y1)/(x2-x1)
= (1-2)/(3-1)
= -1/2
The slope is -1/2
B and D by simplifying the fraction
Answer:
Step-by-step explanation:
Assuming the following data
X: 44, 44, 11, 11, 55
Y: 66, 55, -1, -3, 88
We want to find a linear model
For this case we need to calculate the slope with the following formula:
Where:
So we can find the sums like this:
With these we can find the sums:
And the slope would be:
Nowe we can find the means for x and y like this:
And we can find the intercept using this:
So the line would be given by:
Answer:
13
Step-by-step explanation:
Each row has 4 seats. The bus has 52 seats
52 divided by 4 =13
13 rows = answer
