Question

Graph the equation 4x - 5y = 1 by plotting points using the line tool.

Answer 1

The equation is given to be:

`4x-5y=1`

We can calculate the intercepts of the equation.

At x = 0,

`\begin{gathered} -5y=1 \\ y=-(1)/(5) \\ y=-0.2 \end{gathered}`

At y = 0,

`\begin{gathered} 4x=1 \\ x=(1)/(4) \\ x=0.25 \end{gathered}`

Therefore, the following points can be used to plot the line:

`(0,-0.2)\text{ and }(0.25,0)`

The graph is shown below:
