Answer:

Kindly check explanation

Step-by-step explanation:

Given that:

Number of donuts consumed in a month = y

Age = x

Regression equation obtained :

y=47-1.36x

Meaning of slope of the regression line ;

Comparing the regression equation obtained with the general equation of a linear regression line ;

y = mx + c; where m = slope of the regression line

Hence, the value of slope in the equation is = - 1.36

Thus, the slope can be interpreted as ; The number of donuts consumed in a month is expected to decrease by 1.36 for per(1) increase in age x of consumer.

<u>Given </u><u>:</u><u>-</u>

  • The slope of the line through points (3,y) and (4,10) is 7 .

<u>To </u><u>Find</u><u> </u><u>:</u><u>-</u>

  • The value of y .

<u>Solution</u><u> </u><u>:</u><u>-</u>

As we know that the slope of the line is difference of ordinate divided by the difference of absicca as ,

\longrightarrow m = y -10 / 3 - 4

\longrightarrow 7 (-1) = y -10

\longrightarrow -7 = y -10

\longrightarrow y = 10 -7

\longrightarrow y = 3

<u>Hence</u><u> the</u><u> required</u><u> answer</u><u> is</u><u> </u><u>3.</u>

Write linear equation<br> m=3 and runs through the point (9,2)
sukhopar [10]
To solve the question, use the equation y=mx+b. Since you already know the slope (m), all you need is to find the b. Plug in the x and y from the point (9,2) and m:

2=3(9)+b
2=27+b (subtract 27 on both sides)
b=-25

The equation is y=3x-25
