We are given 4 points.




Using this, we can make an equation.

I got
by using the slope formula.



So the equation we have is 
Now, we can solve for how much peanut butter is used to make 25 packages by plugging in 25 for
, which is the number of cracker packages.


We need to use
teaspoons of peanut butter to make 25 packages of crackers.
Hope this helps.
頑張って!
This is a linear function y=mx + b
If x = 0 then y=b, if A is the point where y intercepts y-axis, the coordinates of
A(0,b)
If you want to shift the graph up by 2 units, then you have to add 2 units to b
In our case original b=7, =so to shift it up, b becomes 7+2=9
and the new function will be y=2x + 9
Answer:
1.627 miles is the difference
Answer:
8
Step-by-step explanation:
average is calculated as
average = 
= 13 ( multiply both sides by 2 )
sum of 2 eldest = 26
Then for the 4 children
average =
=
= 8
