Fistly, calculate the slope of the fuction
Picking any two points on the graph
say points ( 3 , 3) and (2, 0)
[tex]\begin{gathered} \text{slope m = }\frac{\text{change in y}}{\text{change in x }} \\ \\ m\text{ =}\frac{3-0}{3-2} \\ \\ m=\text{ }\frac{3}{1} \\ m\text{ =3} \end{gathered}[/tex]
From the graph, the intercept on y-axis, b is -6
The equation of the line is y = 3x + (-6)
y = 3x - 6
