Question

hello this is the problem that I am stuck on I need the equation but most of all I need to understand where to plot the points on the grass to make my line thank you

Answer 1

Given:

The initial amount of water in the pond = 600 liters

The rate at which water is being added = 25 liters per minute

W represents the amount of water in the pond

T represents the number of minutes that water has been added

The equation that relates W to T is a linear equation where W is the dependent variable and T is the independent variable.

Recall that the general form of a linear equation is:

`\begin{gathered} y\text{ = mx + c} \\ \text{Where m is the slope or the rate of change of y with x} \\ \text{and c is the intercept} \end{gathered}`

For the given problem;

m = 25 litres per minute

c = 600 litres

Hence, the required equation is:

`W\text{ = 25T + 600}`

The graph of the equation is shown below. A few points from the graph has been used to create a table for the graph
