tough to answer, but if slope is only provided then it should intercept at (0,0). Such as, y=3x, that intercepts at 0.

You use point-slope form to find the equation of a line if you only have a point and a slope or if you are just given two point. Usually you will convert point-slope form to slope-intercept form to make it easier to use.
On one of my projects for my algebra class...my professor is asking us to find the slope of a line which is fairly easy.....but i only have one point and it's impossible to find a slope with only one point....what am i doing wrong?

Yes, it is possible only when the x-intercept is infinite. so slope=y/x = 0.
The slope of two lines are perpendicular only if their slopes multiplied together equal -1 (m1*m2 = -1). So if a line has a slope of -3 then a line perpendicular to this one has a slope of -1/-3 or 1/3.
