Answer:
And the slope would be:
Now 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:
And the best option is:
A. y = 0.894x + 0.535
Step-by-step explanation:
We have the following dataset given
x: 5,6,9,10,14
y: 4,6,9,11,12
We want to find the least-squares line appropriate for this data given by this general expresion:
Where m is the slope and b the intercept
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:
And the best option is:
A. y = 0.894x + 0.535
The x - intercept is and y - intercept is (0, 5)
Given that : 3x + y = 5
<em><u>To find: x - intercept and y -intercept</u></em>
The x-intercept is where a line crosses the x-axis, and the y-intercept is the point where the line crosses the y-axis.
To find the x intercept using the equation of the line, plug in 0 for the y variable and solve for x
3x + 0 = 5
3x = 5
Therefore the x - intercept is
To find the y intercept using the equation of the line, plug in 0 for the x variable and solve for y
3(0) + y = 5
y = 5
Therefore y - intercept is (0, 5)
