Question

Draw the graph of 2x-y-4=0 on graph

Answer 1

$\large\underline{\sf{Solution-}}$

Given linear equation is

$\red{\rm :\longmapsto\:2x - y - 4 = 0}$

can be rewritten as

$\red{\rm :\longmapsto\:2x - y = 4}$

Substituting 'x = 0' in the given equation, we get

$\rm :\longmapsto\:2 \times 0 - y = 4$

$\rm :\longmapsto\: 0 - y = 4$

$\rm :\longmapsto\: - y = 4$

$\bf\implies \:y = - 4$

Substituting 'y = 0' in the given equation, we get

$\rm :\longmapsto\:2x - 0 = 4$

$\rm :\longmapsto\:2x = 4$

$\bf\implies \:x = 2$

Substituting 'y = 2' in the given equation, we get

$\rm :\longmapsto\:2x - 2= 4$

$\rm :\longmapsto\:2x= 4 + 2$

$\rm :\longmapsto\:2x= 6$

$\bf\implies \:x = 3$

Hᴇɴᴄᴇ,

➢ Pair of points of the given equation are shown in the below table.

$\begin{gathered}\boxed{\begin{array}{c|c} \bf x & \bf y \\ \frac{\qquad \qquad}{} & \frac{\qquad \qquad}{} \\ \sf 0 & \sf - \: 4 \\ \\ \sf 2 & \sf 0 \\ \\ \sf 3 & \sf 2 \end{array}} \\ \end{gathered}$

➢ Now draw a graph using the points (0 , - 4), (2 , 0) & (3 , 2)

➢ See the attachment graph.

Answer 2

Answer:

The:steps are:-

2x+4=y

y=2x+4

By this we come to know that

x=2

and y intercept is 4
