Question

Draw the graph of equation 5x + 3y = 4 and check whether a) x = 2, y = 5 b) x = −1, y = 3 are solution.

Answer 1

Answer:

R.E.F.Image.

Draw the graph

2x+3y=5

 x 1 7 13 y 1-3 -7 

using this point draw a graph

let x = 1

2(1)+3y=5

3y=5−2

3y=3 

y=1

let x = 7 

2(7)+3y=5

3y=5−14

3y=−9

y=−3

let x = 13 

2(13)+3y=5

26+3y=5

3y=5−26

3y=−21

y=−7

(-3, 4) & put x = -3 

2(−3)+3y=5

−6+3y=5 

3y=11

y=311=4

so (-3, 4) is not solution.

(7,-3) put x = 7

2(7)+3y=5

3y=5−14

3y=−9

y=−3 is solution
