Intergration: Algebra, Writing Equations of Lines

  1. May 23, 2004 #1
    I have two problems that deal with writing an equation in slope-intercept form of a line that satifises certain conditions. Two of such problems my teacher has given me, I have no idea where to start in how to put the conditions in an equation. Can anyone help me in finding out on how to do this?

    1. Perpendicular to the y-axis, passes through (-6, 4)

    2. Parallel to the y-axis, passes through (-7,3)

    Number 1 is easy if you remember that one possibility for y=mx+b is that m=0.

    Number 2 is tough if you have to express the equation with a naked y on the left. On the other hand, if you are allowed to consider x as the dependent variable, then number 2 becomes just as easy as number 1.
