The equation of the line in the graph is
...The equation of the line in the graph is
3y = 4x + 12
3y = 3x + 12
3y = -4x + 12
3y = -4x + 9
Correct answer is C
Gradient of line = Change in yChange in x=y2−y1x2−x1
y2 = 0, 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, multiple through by 3
3y = 4x + 12
