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.
