Equation for CoP: (a)
k= (a)
k= (a)
When finding the CoP in table, ONLY use the first row and do...
y - x
y/x
y + x
y times x
When finding CoP in a graph, find a nice point (where line goes through a corner), draw left to get y, draw down to get x and then do...
y/x
y times x
y + x
y - x
When finding CoP in an equation, solve for y if the equation is not already in the form y=kx. The Cop is then simply _?
CoP
x
y
k
The CoP is used to (a) items/situations that are originally not comparible because they are in simple ratios, not per 1.
When interpretting, the CoP means how many y's per 1 x. So, if you have c=10s where c = cost and s = # of shirts, what does 10 mean?
10 shirts total
$10 total
10 shirts per 1 dollar
