Question

Write the slope-intercept form of equation.


9x + 3y = 27

Answer 1

Slope intercept form:-

• y=mx+b

Now convert

• 9x+3y=27
• 3y=-9x+27
• 3y=3(-3x+9)

Cancel 3

• y=-3x+9

Answer 2

slope intercept form: y = mx + b [ where m is slope and b is y-intercept ]

`\dashrightarrow \ \sf9x + 3y = 27`

`\dashrightarrow \ \sf 3y = 27 -9x`

`\dashrightarrow \ \sf y = (27 -9x)/(3)`

`\dashrightarrow \ \sf y = -3x + 9`

Here, the "slope is -3" and "y-intercept is 9"
