Question

complete the table below to find the solution to linear equation for X Plus y equals -40

Answer 1

You have to complete the table for the solutions of the linear equation

$4x+y=-40$

To do so, replace the equation with each given value of x or y and solve for the missing coordinate:

For x=0

$\begin{gathered} 4x+y=-40 \\ 4\cdot0+y=-40 \\ y=-40 \end{gathered}$

When x=0, y=-40, the coordinates are (0,-40)

For x=2

$\begin{gathered} 4x+y=-40 \\ 4\cdot2+y=-40 \\ 8+y=-40 \\ y=-40-8 \\ y=-48 \end{gathered}$

When x=2, y=-48, the coordinates are (2,-48)

For y=0

$\begin{gathered} 4x+y=-40 \\ 4x+0=-40 \\ 4x=-40 \\ \frac{4x}{4}=-\frac{40}{4} \\ x=-10 \end{gathered}$

When y=0, x=-10, the coordinates are (-10,0)
