You can put this solution on YOUR website! write the standard form of the equation of the line passing thru the given point and having the given slope.
(3,1)1/4
(0,9) 2
(-6,-2), -1/3
(1-3), no slope
------------------
Use y-y1 = m*(x-x1) where m = slope and (x1,y1) is the point
(3,1) 1/4
y-1 = 1/4(x-3)
4y-4 = x-3
x-4y = -1
---------
y-9 = 2x
2x-y = -9
-----------
y+2 = -1/3(x+6)
3y+6 = -x-6
x+3y = -12
--------------
(1-3), no slope (must be (1,-3), and "no slope" is parallel to the y-axis)
x has the same value, regardless of y, so it's
x = 1
