Answer:

Slope = 0.65

y = 0.65x - 10.5

Step-by-step explanation:

Taking the points (-10,-17) and (-8,-15.7)

Slope = Change in y ÷ change in x

Change in y = -15.7 - -17 = 1.3

Change in x = -8 - -10 = 2

Slope = 1.3/2 = 0.65

Taking another point (x,y);

The slope intercept form is;

\frac{y - -17}{x - -10} = 0.65

\frac{y + 17}{x + 10} = 0.65

y + 17 = 0.65x + 6.5

y = 0.65x + 6.5 - 17

y = 0.65x - 10.5

PLZ ANSWER ASAP!!!!! Part B

The equation of the linear regression  is \^ y = 3.58125\^x + 202.575

<h3>Graphing tool</h3>

To determine the line of best fit, we make use of a graphing tool

See attachment for the graph of the line of best fit

<h3>The equation</h3>

From the graphing tool, we have the following calculation summary

  • Sum of X = 440
  • Sum of Y = 3601.5
  • Mean X = 44
  • Mean Y = 360.15
  • Sum of squares (SSX) = 1440
  • Sum of products (SP) = 5157

The regression Equation is then represented as:

\^y = b\^x + a

Where:

b = \frac{SP}{SSX} and a = \bar y - b \times \bar x

b = \frac{5157}{1440}

b = 3.58125

Also, we have:

a = \bar y - b \times \bar x

a= 360.15 - (3.58\times 44)

a = 202.575

So, the linear regression equation is:

\^ y = 3.58125\^x + 202.575

M<br> (9x + 2)<br> 1<br> (5х – 1)°<br> 740<br> What is mz2?<br> 39°<br> 570<br> ОООО<br> 67°<br> 740
Elodia [21]

Answer:

<h3>           m∠2 = 67°</h3>

Step-by-step explanation:

m║n   ⇒   (9x + 2)° = 74°       {Corresponding Angles}

(9x)° = 72°

 x = 8

Angles: angle corresponding to angle (5x-1)°, angle 74° and angle 2 add to 180° (straight angle)

(5×8 - 1)° + 74° + m∠2 = 180°

39° + 74° + m∠2 = 180°

113° + m∠2 = 180°

m∠2 = 180° - 113°

m∠2 = 67°
