Question

If the point P (2,-7) lies on the line 4x + my = 22 then what will be the value
of m?​

Answer 1

Answer:

we know p(2,-7)which meansp(x,y)

therefore x=2,y=-7

4x+my=22

4(2)+(-7)m =22

8-7m=22

-7m=22-8

-7m=14

m=-2 is the answer..

Answer 2

Answer:

The value of m = -2

Step-by-step explanation:

• If the point lies on the line then it should satisfy the equation.
  $4x+my=22$
• So according tho the Question x = 2 and y = -7
• Putting these values in the equation we get
  $4*2+m*(-7) = 22\\22-8 = -7m\\-2 = m$
• Hence we get the value of m = -2
