Question

Can someone step by step turn 3y-9x=-81 into slope-intercept form!???

Answer 1

To turn something into the slope-intercept form

⇒ must know the slope-intercept form ⇒
`y = mx +b`

• m: the value of the slope
• b: y-intercept

To convert our current form into slope-intercept form

⇒ must solve for 'y'

⇒ (in other words) move everything to one side and 'y' by itself on the

other

`3y - 9x = -81\\3y =9x-81\\y = 3x - 27`

*purely extra information (not necessary for final answer)

• slope is 3
• y-intercept is -27

Slope-intercept form: y = 3x - 27

Hope that helps!
