The graph shows a proportional relationship between y (price) and x (number of pounds of rice).

A graph with a line running through coordinates (0,0) and coordinates (30,24)



What is the unit rate, expressed in price per pound?

a. $0.60
b. $0.80​
c. ​$1.25
d. ​$1.67









Respuesta :

The answer is c. $1.25

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The unit rate, expressed in price per pound is $0.80​.

What is the equation of a line?

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of a line is given by,

y =mx + c

where,

x is the coordinate of the x-axis,

y is the coordinate of the y-axis,

m is the slope of the line, and

c is constant.

The slope of the line running through coordinates (0,0) and coordinates (30,24) is,

m= (24-0)/(30-0) = 0.8

Hence, the unit rate, expressed in price per pound is $0.80​.
