>>find the slope and y-intercept of each line. graph the line.
`
-x+3y=6<<
`
To find the slope of a line, solve it for y, which puts it in the form
`
y = mx + b
`
and then the coefficient of x, is the slope m,a nd the number b tells us
that the y-intercept is (0, b)
`
-x + 3y = 6
`
Add x to both sides
`
3y = x + 6
`
Multiply every term by 1/3
`
1/3�3y = 1/3�x + 1/3�6
`
y = 1/3�x + 2
`
This is in the slope-intercept form
`
y = mx + b
`
The coefficient of x is 1/3, so the slope, m, is 1/3
The term b = 2 tells us that the y-intercept is (0,b) or (0,2)
`
Graph:
