Question

1. Draw The graph of x + y = 8​

Answer 1

Explanation:

There are two ways of doing it.

One

→

The intercept form of the equation is

x

a

+

y

b

=

1

, where

a

and

b

are the intercepts formed by the line on

x

-axis and

y

-axis.

As the equation is

x

+

y

=

8

, dividing each term by

8

, we get

x

8

+

y

8

=

1

and hence, intercepts formed by the line on

x

-axis is

8

and on

y

-axis too it is

8

. Hence mark the intercepts

8

on each axis and join them to draw the graph of

x

+

y

=

8

.

Two

→

Just put

x

=

0

to get

y

-intercept, it comes out as

8

, and put

y

=

0

to get

x

-intercept, which too comes out as

8

.

Now as above mark the two intercepts and join to form line.

graph{((x-8)^2+y^2-0.025)((y-8)^2+x^2-0.025)(x+y-8)=0 [-7.79, 12.21, -1.32, 8.68]}

Answer 2

Answer:

x+y=8

1. x=-1

-1+y=8

y=8+1

y=9 (-1,9)

2. x=1

1+y=8

y=8-1

y=7(1,7)

3. x=8

8+y=8

y=8-8

y=0 (8,0)

substitute any integer in the equation 'x' place
