The equation of the line in the graph is
A. 3y = 3x + 12
B. 3y = 3x + 12
C. 3y = -4x + 12
D. 3y = -4x + 9
Correct Option: Answer is A
Solution:

Gradient = y_(2 – y_1 )/(x_2- x_1 )
y2 = 0; y1 = 4
x2 = 3 ; x1 = 0
= y_(2 – y_1 )/(x_2- x_1 ) = (0-4)/(3-0)= (-4)/3
Equation of straight line y = mx + c
Where m = gradient and c = y
intercept = 4
y = 4x + 4/3 multiply through y
3y = 4x + 12
