What is the equation of the line x–3y=18in slope-intercept form?
Alekssandra [29.7K]

Answer:

y=\frac{1}{3} x-6

Step-by-step explanation:

Write down the slope-intercept form:

y=mx+b

Where m is the slope and b is the y-intercept.

To turn the equation into slope-intercept form, isolate y on the left-hand side:

x-3y=18\\-3y=18-x\\y=-6+\frac{x}{3} \\

Rearrange the equation a bit:

y=\frac{1}{3} x-6
