Question

Find the value of , if the line 3 = + 7 passes through the point (1,2). Find a solution for the above equation. How many such solutions are possible?

Answer 1

Answer:

for (3,4)

take x=3 nd y= 4 so.. 3y = ax +7 3 x 4 = ax 3 +7

→ 12 = 3a +7

→⇒ 12-7= 3a

⇒ 5 = 3a

⇒ 5÷3=a

⇒ a = 1.67

for (1,2) as per above → a=-1 for (2,-3) as per above → a= -8
