Question

Y'
FREQUENCY POLYGON
Scale: 1cm = 5unit on
the Y - axis​

Answer 1

Answer:

3x+5y=12

⟹3x=12−5y

⟹x=

3

12−5y

Let, y=3, then x=

3

12−5(3)

=−1

Similarly,when y=0,x=4 and y=−6,x=6

3x−5y+18=0

⟹3x=−18+5y

⟹x=

3

−18+5y

Let, y=3, then x=

3

−18+5(3)

=−1

Similarly, when, y=0,x=−6 and y=6,x=4

∴ the intersecting point is x=−1,y=3
