Question

Find the area (in square units) of the triangle formed by the graph of x=4, y=3 and 3x+4y=12

Answer 1

given equation is=2x+3y=6---(1)

we rewrite the equation ,=3y=-2x+6

                                       y=-(2/3)x+2  

in these equation,slope=-2/3

the coordinating point here is  (o,2)  

set y=0 then  ,0=-(2/3)x+2

                      2/3x=2

                          x=3

here the coordinating point is,(3,0)

using this coordinate we draw one graph,then

from the graph height will be come,2

and length will be come,3

area =2*3/2=3
