5 Match The Equation With Its Graph4x 8y 32 class=

Answer :

In order to find the corresponding graph, let's find two points that are on the line.

To do so, let's choose values of x and then calculate the corresponding values of y:

[tex]\begin{gathered} x=0\colon \\ 0+8y=32 \\ y=\frac{32}{8}=4 \\ \\ x=8\colon \\ 32+8y=32 \\ 8y=0\to y=0 \end{gathered}[/tex]

So we have the points (0, 4) and (8, 0).

Looking at the options, the graph that has these points is the fourth graph.
