Point -slope form of a straight:
we have a point (x₀,y₀) and the slope m.
y-y₀=m(x-x₀)
Given two points (x₁,y₁) and (x₂,y₂) the slope will be:
m=(y₂-y₁)/( x₂-x₁) or m=(y₁-y₂)/(x₁-x₂)
In this case:
(2,3)
(4,4)
m=(4-3) / (4-2)=1/2
we can choose the point (2,3) or the point (4,4); the result will be the same.
y-y₀=m(x-x₀)
y-4=1/2(x-4)
y=1/2 x-2+4
y=1/2 x + 2
Answer: the funciton passes through the poinsts (2,3) and (4,4) is:
y=1/2 x+2
Rule of thumb in basic rounding is 5 above round up, below five don’t round up.
To round to the nearest thousand, you look at the hundred place. What is the number nearest to?
71,903 Is rounded up to 72,000
^
25,368 is rounded to 25,000
^
72,000 - 25,000 = 47,000
$709.21
$361.36 for week one + $347.85 for week two = $709.21 total for both weeks
