Given the line of the best fit for a set of data points with equation y=-5x-2.5 what is the residual for the point (3,6)

HACTEHA [7]

Answer:

The residual of the point $(3,6)$ in the equation $y=-5(x)-2.5$ is $= 23.5$

Step-by-step explanation:

We have been given point $(3,6)$ where $x=3$ .

Now the equation is $y=-5(x)-2.5$ .

Plugging the value of $x=3$ in the equation of $y=-5(x)-2.5$ ,

we have to find the predicted value of y and $y=-5(3)-2.5 =-15-2.5=-17.5$ .

So y predicted $=-17.5$ .

To find the residual point we have to subtract the actual value from the predicted value.

As actual value of $y=6$ along with the points $(3,6)$ .

Residual point = Actual value - Predicted value.

$=6 -(-17.5) =23.5$

So the residual for the point $(3,6)$ is $23.5$ .

Let's use the quadratic formula
$\frac{ - b( + - ) \sqrt{ {b}^{2} - 4ac} }{4a}$
a = 1, b = 0, c = -18
$\frac{ - (0)( + - ) \sqrt{ {(0)}^{2} - 4(1)( - 18)} } {4(1)} \\ \frac{( + - ) \sqrt{72} }{4}$
This is now split into two equations:
$\frac{ + \sqrt{72} }{4}$
and
$\frac{ - \sqrt{72} }{4}$
Since $\frac{ \sqrt{72} }{4} \\ = \frac{6 \sqrt{2} }{4} \\ = \frac{3 \sqrt{2} }{2}$
The answer is
$\frac{3 \sqrt{2} }{2} \: and \: \frac{ - 3 \sqrt{2} }{2}$
which means there are 2 real number solutions to the problem: answer B.
