Question

Point (3,2) lies on the line ax+2y=10 then find the value of a

Answer 1

a = 2

Explanation:

given the point (3, 2 ) lies on the line ax + 2y = 10 , then

the coordinates of the point make the equation true

substitute x = 3, y = 2 into the equation and solve for a

3a + 2(2) = 10

3a + 4 = 10 ( subtract 4 from both sides )

3a = 6 ( divide both sides by 3 )

a = 2
