Question

show the graph of 3x Sy-157​

Answer 1

Answer:

Taking 1 cm = 1 uni

Plotting equation 3x+y+5=0

Let y=4 then,

=>3x+4=−5

=>3x=−9

=>x=−3

One point is (−3,4)

Let y=1 then,

=>3(1)+y+5=0

=>y=−8

Other point is (1,−8)

Plotting equation 3y−x=5

Let y=2

=>3(2)−x=5

=>x=1

One point is (1.2)

Let x=−5 then,

=>3y−(−5)=5

=>y=0

Other point is (−5,0)

Plotting equation 2x+5y=1

Let x=−2 then,

=>2(−2)+5y=1

=>5y=1+5

=>y=1

One point is (−2,1)

Let y=−1 then,

=>2x+5(−1)=1

=>x=3

The other point is (3,−1)

The point of intersection (−2,1) and the lines given by the equations are concurrent
