Explanation
[tex]4x+2y=-14[/tex]
Step 1
isolate y
a)subtract 4x in both sides
[tex]\begin{gathered} 4x+2y=-14 \\ 4x+2y-4x=-14-4x \\ 2y=-4x-14 \end{gathered}[/tex]
b) divide both sides by 2
[tex]\begin{gathered} \frac{2y}{2}=\frac{-4x-14}{2} \\ y=-2x-7 \end{gathered}[/tex]
Step 2
now, find 2 points of that line
when x=0
[tex]\begin{gathered} y=-2x-7 \\ y=-2\cdot0-7 \\ y=0-7 \\ y=-7 \\ (0,-7)P1 \end{gathered}[/tex]
when x=-2
[tex]\begin{gathered} y=-2x-7 \\ y=-2(-2)-7 \\ y=4-7 \\ y=-3 \\ (-2,-3)P2 \end{gathered}[/tex]
Step 3
draw
