Answer:
y= 1/2x-1
Step-by-step explanation:
The equation of a line is y= mx+c
m represents the slope of the line
c represents the y-intercept
So we plug in our information into the equation.
The slope is 1/2 so y= 1/2x + c
The line crosses at (0,-1) which makes -1 the y-intercept as the line crosses at this point on the y-axis.
Therefore, y= 1/2x-1
Answer:
Step-by-step explanation:
Rewrite -x-2y= -10 as -2y= x - 10 and then as y = (-1/2)x + 5.
Then choose any 3 x values and find the corresponding y values using this formula. For example:
x y = (-1/2)x + 5 (x, y)
----- -------------------- ---------
0 5 (0, 5)
-4 (-1/2)(-4) + 5 = 7 (-4, 7)
6 (-1/2)(6) + 5 = 2 (6, 2)
Plot these three points and then draw a line through them.
Answer:
87.08% percentage of families spend more than $4000 annually on food and drink
Step-by-step explanation:
Given -
average annual expenditure on food and drink for all families is $5700
Mean 
= 5700
standard deviation 
= 1500
Let X be the no of families spend annually on food and drink
percentage of families spend more than $4000 annually on food and drink =
= 
= 
Using 
= 1 - 
= 1 - .1292
= .8708
= 87.08%
