The correct option is B, The P-intercept, 31, means that Tuyet's monthly water bill payment would be 31 dollars if he used no water.
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 the y-intercept.
Given that the equation P = 31+ 1.75w models the relation between the amount of Tuyet's monthly water bill payment, P, in dollars, and the number of units of water, w, used. Therefore, the interpretation of the P-intercept of the equation is that the P-intercept, 31, means that Tuyet's monthly water bill payment would be 31 dollars if he used no water.
Hence, the interpretation of the P-intercept of the equation is that the P-intercept, 31, means that Tuyet's monthly water bill payment would be 31 dollars if he used no water.
