Answer:
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
Let
x -----> the number of pumpkins (independent variable or input value)
y ----> the cost of the pumpkins (dependent variable or output value)
we have that
For x=4, y=11
Find the value of the constant of proportionality k
The linear equation is
