Given:
The equation is 5x - 4y = -18
Required:
Graph the linear equation. Find three points that solve the equation, then plot
on the graph.
Explanation:
The given equation is:
5x - 4y = -18
subsitute x = 0
[tex]\begin{gathered} 5\times0-4y=-18 \\ -4y=-18 \\ 4y=18 \\ y=\frac{18}{4} \\ y=\frac{9}{2} \end{gathered}[/tex]Substitute x = -1
[tex]\begin{gathered} 5\times-1-4y=-18 \\ -5-4y=-18 \\ -4y=-18+5 \\ -4y=-13 \\ 4y=13 \\ y=\frac{13}{4} \end{gathered}[/tex]substitute x= 1
[tex]\begin{gathered} 5\times1-4y=-18 \\ 5-4y=-18 \\ -4y=-18-5 \\ -4y=-23 \\ y=\frac{23}{4} \end{gathered}[/tex]The graph of the equation is:
Final answer:
Graph attached in the explanation part.
