Five pounds of rice at a store cost $6.50.use the ray tool to graph the cost, c, vs pounds of rice, p, at this store. how do i plot this on a graph?

for every 5 pounds the price increses by 6.50

 so points (5,6.50) (10,13) 15,19.50) etc.

we know that

A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form or

Let

c--------> the cost in dollars

p-------> the pounds of rice

the unit rate in this problem is equal to the slope of the linear equation

Find the unit rate

the equation of the direct variation is equal to

using a graphing tool

see the attached figure

the answer in the attached figure

the one that has a slope of 1/2 and is positive.

step-by-step explanation: 2 buckets 1 trip ; 4 buckets 2 trips and so on.
