It’s the second one because if you look at the averages you can see no ruff stuff is more expensive so then you just do subtraction to find how much more expensive it is
Answer:
The slope of the line between these two points is 1.50.
Step-by-step explanation:
The general form of the regression line is:

Here,
<em>y</em> = dependent variable
<em>x</em> = independent variable
<em>m</em> = slope
<em>c</em> = intercept.
The formula to compute slope using two-point method is:

In this case the dependent variable is the cost per week to feed and independent variable is the weight of the hamster.
The two points are:
(<em>x</em>₁, <em>y</em>₁) = (3, 3.50)
(<em>x</em>₂, <em>y</em>₂) = (4.8, 6.20)
Compute the slope as follows:




Thus, the slope of the line between these two points is 1.50.
Answer:
suppose length is x
breadth is y
now,
x.y=18
2(x+y)= 18
x= 3
y=6
