Question

how to make graphs of the following equations 2x+y+3=0

Answer 1

take x=o ,x=1,x=-1,x=2 ,x=-2.. substitute the value of X in the equation u will get the value of y and u can mark those values on graph

Answer 2

The Following Steps will be Solved below.

2x+y+3 =0

2x+y = (-3) [by transferring digit 3 from right hand side to left hand side]

[So, the sign of 3 will get reversed]

x+y = (-3)/2 [we will reciprocal the sign of digit 2]

so, x+y= (-1.5)

Now Assuming the value of:

x=1, the value of y= -1.5-1

= (-2.5)

Similarly, Assuming

x=2, the value of y = -1.5-2

= -3.5

Continue the following steps and plot then on the graph and you will be able to do it.
