Method 1
the easiest way to find out the slope and y-intercept is to put the equation into slope-intercept form. You will probably be quizzed on this term throughout high school and college so make sure you know it.
Slope-intercept form is
where (x,y) is any given point
m=slope
b=the y-intercept
.
Given: Solve for y
subtract 3x and subtract 1 from both sides
combine like terms
divide both sides by 3
.
reduce and seperate the numbers on the right to fit the correct form
or
.
Method 2
find the slope and the y-intercept
to find the y-intercept let x=0 , and find y=?
.
3y+3(0)+1=0
3y+1=0
3y=-1
y=-1/3
.
You need another point to determine slope so find the x-intercept by letting y=0 and solving for x
.
3(0)+3x+1=0
3x+1=0
3x=-1
x=-1/3
.
