Question

Solve graphically X+y=4 Solve the ploat also

Answer 1

Answer:

Let's put this into slope-intercept form to make graphing easier. The general equation for that form is:

y

=

m

x

+

b

where m is the slope and b is the y-intercept. So we'll get:

x

+

y

=

4

y

=

−

x

+

4

The y-intercept is 4, so that's a point

(

0

,

4

)

.

The slope is

−

1

, so the graph will move one point down for every point it moves right. The next point we can graph is

(

1

,

3

)

. Use a straightedge to connect those two dots and make the graph. It'll look like this:

graph{-x+4 [-10, 10, -5, 5]}

Answer 2

Step-by-step explanation:

Equation (i) is x+y=4

i.e. y=4−x and

3x−2y=−3

i.e y=

2

(3x+3)

We draw the graphs.

From the graph (x,y)=(1,3)

The required area is a triangle
