Tamara was asked to write an example of a linear functional relationship. She wrote this example:

Llana [10]

Answer:

Tamara's example is in fact an example that represents a linear functional relationship.

This is because the cost of baby-sitting is linearly related to the amount of hours the nany spend with the child: the more hours the nany spends with the child, the higher the cost of baby-sitting, and this relation is constant: for every extra hour the cost increases at a constant rate of $6.5.

If we want to represent the total cost of baby-sitting in a graph, taking the variable "y" as the total cost of baby-sitting and the variable "x" as the amount of hours the nany remains with the baby, y=5+6.5x (see the graph attached).
The relation is linear because the cost increases proportionally with the amount of hours ($6.5 per hour).
See table attached, were you can see the increses in total cost of baby sitting (y) when the amount of hours (x) increases.

If the , points on the graphs are (-4,1) and (2,1) what is the equation ?

balandron [24]

Slope-intercept form:

y = mx + b

"m" is the slope, "b" is the y-intercept

To find "m", you can use the slope formula and plug in the two points:

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

$m=\frac{1-1}{2-(-4)}$

$m=\frac{1-1}{2+4}$

$m=\frac{0}{6}=0$

The slope is 0 so:

y = mx + b

y = 0x + b [any number multiplied by 0 is 0]

y = b

To find "b", you plug in either of the points into the equation (since both of their y values are 1]

y = b

1 = b

Your equation is:

y = 1 (This is a horizontal line)

The population parameters that describe the y-intercept and slope of the line relating y and x, respectively, are _____. Group o

ololo11 [35]

B0 AND B1 are the parameters which describes the intercept and slope of the lines.

According to statement

we have to find the parameters which describes the intercept and slopes.

Simple linear regression is a model that estimates the relationship between one independent variable and one dependent variable using a straight line. Both variables should be quantitative.

So, B0 AND B1 are the parameters which describes the intercept and slope of the lines.
