For this case, the first thing you should keep in mind is that the generic equation of the line is:

\(y = mx + b
\)

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:

\(y = 3x
\)

Therefore we have:

\(m = 3
\)

This means that 3 tomatoes are added for each 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.
