Question

Draw the graph of the equation $2x+3y=11$. Find the value of $y$ when $x=1$ from the graph.

Answer 1

Given that,

$2x+3y=11$

$2x+3y=11$

$2x=11-3y$

$x=\frac{11-3y}{2}$

Now lets form the plot points,

$\begin{array}{ccc}y& 1& 2\\ x& 4& 2.5\end{array}.$

Now, lets draw the graph

From the graph, when $x=1$ then $y=3$.
