Write the equation of the line with a slope of -1/3 and passing through the point (6, -4).
Write the equation of the line passing through the points (0, -4) and (-2, 2).
Write the equation of the line passing through the points (-6,1) and (-4,2).
Write the equation of the line with an undefined slope, passing through the point (2, 5). Hint: refer back to lesson 4.04 for help with this one.

You can put this solution on YOUR website! Write the equation of the line with a slope of -5 and a y-intercept of (0,3).
-----------------
y = mx + b
y = -5x + 3
Nothing to figure out.
-------------------------
Write the equation of the line with a slope of -1/3 and passing through the point (6,-4).
----------
Use y = mx + b and the point to find b
-4 = (-1/3)*6 + b
Find b, then it's the same as the 1st problem.
-----------------
Write the equation of the line passing through the points (0,-4) and (-2,2)
-------------
Find the slope, m = diffy/diffx
Then use y = mx + b and either point to find b.
Then it's the 1st problem again.
----------------
Write the equation of the line passing through the points (-6,1) and (-4,2)
---------
Same as the preceding problem.
------------
Write the equation of the line with an undefined slope, passing through the point (2,5). Hint: refer back to lesson 4.04 for help with this one.
---------
Undefined is parallel to the y-axis, so the x value is constant.
x = 2 is the equation.
