Which rate shows the price at which joanna sells tomatoes?

Answer is B. $ 1.20 per pound

Step-by-step explanation:

It is evident from the graph in which prices have been plotted on Y axis and weight on X axis.

Now we can see clearly from the graph that 5 pounds of Tomatoes were costing 6 dollars and 10 pounds were costing 12 dollars.

Therefore selling price of the tomatoes will be = Total price/weight of tomatoes

So selling price =6/5 or 12/10

Now by solving this selling price= $ 1.2 per pound

y/x=18

step-by-step explanation:

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
