Answer:
Explanation:
A linear equation can be graphed in a simple manner. We just have to find two points that lie on the line of the equation and then connect them to produce a line.
Now what two points lie on 7x + 3y = 12?
Well, let us pick a point where x = 0. What is the y-coordinate? Putting x = 0 into our equation gives
[tex]\begin{gathered} 7(0)+3y=12 \\ 3y=12 \end{gathered}[/tex]diving both sides by 3 gives
[tex]\begin{gathered} y=12/3 \\ y=4 \end{gathered}[/tex]Hence a point with x = 0, y= 4 lies on the line. In other words, (0, 4) lies on the line.
We now need to find a second point that lies on the line. How about
