=0,b
=0
Answer:
$2 price per pound
2 is the constant of proportionality
Step-by-step explanation:
Price of Cherries = $2 per pound
what is the constant of proportionality
If y = total cost of buying x pounds of Cherries at $2 per pound
The equation below represent the situation
y = $2 * x
y = 2x
The constant of proportionality is 2
That is, the $2 price per pound
Coefficients are ,5,20 variables are w,m and constant is 50
Eq. of line through (1,2) and (4,5) is
x-y+1=0
