Question

5. Match the equation with its graph.4x + 8y = 32

Answer 1

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:

`\begin{gathered} x=0\colon \\ 0+8y=32 \\ y=(32)/(8)=4 \\ \\ x=8\colon \\ 32+8y=32 \\ 8y=0\to y=0 \end{gathered}`

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

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