slope intercept form: y = mx + b [ where m is slope and b is y-intercept ]
[tex]\dashrightarrow \ \sf9x + 3y = 27[/tex]
[tex]\dashrightarrow \ \sf 3y = 27 -9x[/tex]
[tex]\dashrightarrow \ \sf y = \dfrac{27 -9x}{3}[/tex]
[tex]\dashrightarrow \ \sf y = -3x + 9[/tex]
Here, the "slope is -3" and "y-intercept is 9"
