Answer :
For this case, the first thing you should keep in mind is that the generic equation of the line is:
[tex] y = mx + b
[/tex]
Where,
m: slope of the line or rate of cam.
b: cutting point with vertical axis.
We note that for this case, the equation of the line is:
[tex] y = 3x
[/tex]
Therefore we have:
[tex] m = 3
[/tex]
This means that 3 tomatoes are added for each teaspoon of salt.
Answer:
A. 3 tomatoes per teaspoon of salt
The unit rate for the situation is 3 tomatoes per teaspoon of salt.
The equation of a straight line is given by:
y = mx + b;
where m is the slope of the line, b is the y intercept and y, x are variables.
y represent the number of tomatoes added and x represent the number of teaspoon of salt.
Given the equation of the line is: y = 3x
The unit rate of the graph is equal to the slope of the graph (i.e. 3). Hence:
The unit rate for the situation is 3 tomatoes per teaspoon of salt.
