Can a set of data have more than one line of best fit? Why or why not?

Answers

Line of best fit refers to a line through a scatter plot of data points that best expresses the relationship between those points. Statisticians typically use the least squares method to arrive at the geometric equation for the line, either though manual calculations or regression analysis software. A straight line will result from a simple linear regression analysis of two or more independent variables. A regression involving multiple related variables can produce a curved line in some cases.

What is the slope of the line that passes through the points (48, 10) and (-36, 17)?

Answers

Answer:

y = m x + b      equation of a straight line

m = (y2 - y1) / (x2 - x1)     slope of line

m = (17 - 10) / (-36 - 48) = 7 / -84 = -1 / 12

y = -x / 12 + b     equation of line

Or b = y + x / 12

If y =  10 and x = 48 then    b = 10 + 48 / 4 = 14

if  y = 17 and x = -36 then b = 17 - 36 / 12 = 14

So b = 14 and   y = -x / 12 + 14

Solve for the value of z.

Answers

Answer:

z=75

Step-by-step explanation:

Answer:Z=75

Step-by-step explanation: Since the line is a straight angle, and all straight angles are equal to 180 degrees, you can start building an equation by setting both 101 degrees and (z+4) degrees to equal 180.

Your equation will then be (z+4)+101=180

Add like terms to get z+105=180
Subtract using the subtraction property of equality to get z=75

Hope this helps and good luck with your future courses!
