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 answer is C
Gradient of line = Change in yChange in x = y2−Yx2−x
y2 = 01
Y1 = 4
x2 = 3 and x1 = 0
y2−y1x2−x1=0−43−0=−43
Equation of straight line y = mx + c
Where m = gradient and c = y
intercept = 4
y = 4x + 43 multiply through y
3y = 4x + 23
