    Let, P(x)=2x+3y=11-(1) P(x)=2x-4y=-24-(2) Now solving 1 and 2 we get 7y=35 Y=5 Now putting the value of y in 1 we get X=-2 Now,given y=MX+3 5=m(-2)+3 M=-1

    2x + 3y = 11 (1) 2x - 4y = -24 (2) Subtracting both the equations 7y = 35 y = 5 Putting y = 5 in 1 we get 2x + 15 = 11 2x = -4 x = -2 y = mx + 3 5 = m(-2) + 3 2 = -2m -1 = m
