Question 117156: I have my final tomorrow and cannot figure these problems out. I need to know HOW to work the problem out.
1. Find the slope and the y-intercept for the follwing equation of a line.
y=1/3x-2/3
2. same as above but for 6x + 3y = 12 Found 2 solutions by jim_thompson5910, stanbon:Answer by jim_thompson5910(35256) (Show Source): You can put this solution on YOUR website! #1
Let's use the general equation where m is the slope and b is the y-intercept
Convert from standard form (Ax+By = C) to slope-intercept form (y = mx+b)
Start with the given equation
Subtract 6x from both sides
Simplify
Divide both sides by 3 to isolate y
Break up the fraction on the right hand side
Reduce and simplify
The original equation (standard form) is equivalent to (slope-intercept form)
The equation is in the form where is the slope and is the y intercept.
Answer by stanbon(75887) (Show Source): You can put this solution on YOUR website! 1. Find the slope and the y-intercept for the follwing equation of a line.
y=1/3x-2/3
------------------
the equation is in slope-intercept form
the slope is (1/3); the intercept is (-2/3)
------------------------------------------
2. same as above but for 6x + 3y = 12
Solve for y:
3y = -6x + 12
y = -2x + 4
slope is -2 ; intercept is 4
