Answer:


x+3y=8

Explanation:

From inspection of the given graph, two points on the line are:

  • (-4, 4)
  • (-1, 3)

Substitute these points into the slope formula to calculate the slope of the line:


\implies \textsf{slope}\:(m)=(y_2-y_1)/(x_2-x_1)=(3-4)/(-1-(-4))=-(1)/(3)

Substitute the found slope and one of the points into the point-slope formula:


\implies y-y_1=m(x-x_1)


\implies y-4=-(1)/(3)(x-(-4))


\implies y-4=-(1)/(3)(x+4)


\boxed{\begin{minipage}{5.5 cm}\underline{Standard form of a linear equation}\\\\$Ax+By=C$\\\\where:\\ \phantom{ww}$\bullet$ $A, B$ and $C$ are constants. \\ \phantom{ww}$\bullet$ $A$ must be positive.\\\end{minipage}}

Multiply both sides by 3:


\implies 3(y-4)=3 \cdot -(1)/(3)(x+4)


\implies 3y-12=-(x+4)


\implies 3y-12=-x-4

Add x to both sides:


\implies 3y-12+x=-x-4+x


\implies 3y-12+x=-4

Add 12 to both sides:


\implies 3y-12+x+12=-4+12


\implies x+3y=8
