Question

Give the equation of the boundary line of the following Inequality. 4x+5y>36 O y=(-4/5)x+(3675) 45

Answer 1

The inequality is:

`4x+5y>36`

To find the equation of the boundary line we need change the inequality sign for an equal sign and solve for y.

`\begin{gathered} 4x+5y=36 \\ 5y=-4x+36 \\ y=-(4)/(5)x+(36)/(5) \end{gathered}`

Therefore, the boundary line is:

`y=-(4)/(5)x+(36)/(5)`
