If the point (2, 5) lies on the graph of 3y = ax + 7, then find the value of a
x = 2, y = 5 is a solution of the equation 3y = ax + 7
(3x5) = 2a + 7
2a = (3x5) – 7 = 8
a = 4
If the point (3,4) lies on the graph of equation 3y — ax+7 find the value of a
If the point (3, 4) lies on the graph of 3y = ax + 7 then the value of a is
(a) 25
(b) 53
(c) 35
(d) 27
