Explanation:
Step-by-step explanation:
Refer the attachment for graph.
Equation given : 3x + 4y = 6
\sf{\longrightarrow} \: 3x + 4y = 6⟶3x+4y=6
\sf{\longrightarrow} \: 3x= 6 - 4y⟶3x=6−4y
\sf{\longrightarrow} \:x = \dfrac{6 - 4y}{3}⟶x=36−4y
When y = 0
\sf{\longrightarrow} \:x = \dfrac{6 - 4(0)}{3} = \dfrac{6}{3}⟶x=36−4(0)=36
\sf{\longrightarrow} \:x = 2⟶x=2
When y = 3
\sf{\longrightarrow} \:x = \dfrac{6 - 4(3)}{3} = \dfrac{ - 6}{3}⟶x=36−4(3)=3−6
\sf{\longrightarrow} \:x = - 2⟶x=−2
When y = 6
\sf{\longrightarrow} \:x = \dfrac{6 - 4(6)}{3} = \dfrac{ - 18}{3}⟶x=36−4(6)=3−18
\sf{\longrightarrow} \:x = - 6⟶x=−6
Solutions for 3x + 4y = 6,
\begin{gathered}\begin{tabular}{|c|c|c|c|}\cline{1-4} x&2&-2&-6\\\cline{1-4}\ y&0&3&6\\\cline{1-4}\end{tabular}\end{gathered}

Question a)
The graph cuts x-axis at (2,0) and y-axis at (0,1.5)

Question b)
There is a triangle formed.
\sf{Area \: of \: Triangle = \frac{1}{2} \times Base \times Height}AreaofTriangle=21×Base×Height
Base = 2 units
Height = 1.5 units
\sf{\longrightarrow} \: \dfrac{1}{2} \times 2 \times 1.5⟶21×2×1.5
\sf{\longrightarrow} \: 1 \times 1.5⟶1×1.5
\sf{\longrightarrow} \:1.5 \: sq. \: units⟶1.5sq.units
Area of the enclosed figure is 1.5 sq. units.
