Question

draw the graph of equation x - y + 3 =0 use it to find some solution of the equation and check from the graph x = 0 and Y =3 is a solution draw the graph

Answer 1

x - y + 3 = 0

If x = 0

0 - y + 3 = 0

y = 3

(0,3)   --------------- (1)

Now x = 1

1 - y + 3 = 0

y = 4

x = (1,4)  -------------- (2)

x = -1

-1 -y + 3 = 0

y = 2

x = (-1, 2)  ----------------(3)

Like this you can take 2, -2 etc.

Now draw a graph in plus shape (+). Sleeping line is x axis and y is straight line. Middle point Which x and y axis meet is zero. Mark 0, then on sleeping line(x axiis) on right side of the zero mark 1, 2, 3, 4 , 5, 6 ------ . Now left side of the zero mark -1, -2, -3, -4 ----- . Now on y axis the is straight line above zero mark 1, 2, 3, 4, 5----- and downwards mark -1, -2, -3, -4 -------.

Now take first answer (0,3) find 0 on x axis and look for 3 on y axis. Mark on 3 because x=0.

Now second one (1, 4). find 1 on x axis  and draw a straight line from there with pencil to up. And now find 4 on y axix. From there draw a sleeping line. Now there will a point both line meets. that is (1,4). please rub ines. Like this find each meeting points without drawing lines. After finding each points draw a line by connecting each dots. it will look like slanding line.. On the side of this slanding line pls write your equation x - y +3 = 0

I hope you understood now

Answer 2

1. x + y + 3 = 0 x = 0| 1 | 2

y = 3| 2 | 1

0 + y + 3

y =3

2. x + y + 3 = 0

1 + y + 3

y = 3 - 1

y = 2

3. x + y +3 = 0

2 + y + 3

y= 3 - 2

y = 1
