Question

Solve graphically 3x - 2y = 6 and 3x + y = 15 Find the coordinates of the vertices of the triangle formed by these lines and x-axis.​

Answer 1

Step-by-step explanation:

(a)3x-2y=6

Putting x=0

0-2y=6

y=-3

Their co-ordinate=(0,-3)

Putting y=0

3x-0=6

x=2

Their co-ordinate=(2,0)

(b)3x+y=15

Putting x=0

0+y=15

y=15

Their co-ordinate=(0,15)

Putting y=0

3x+0=15

x=5

Their co-ordinate=(5,0)
