Question

Find the value of m , If A(2, 1) lies on the graph of the equation 2x + 3y = m . Also identify whether (-1, 3) lies on the same graph.

Answer 1

Answer:

Step-by-step explanation:

2x+3y=m

Substitute x=2 and y=1 in this equation

2(2)+3(1)=m

m=7

Now ,

2x+3y=p(say for x=-1 and y=3)

2(-1)+3(3)=p

P=7,now m=p

Therefore (-1,3) lies on same graph
