    straight line : y = mx + c quadratic line: y = ax^2 + bc + c circular line: x^2 + y^2 = 1

    you need at least 2 points to work out the equation of a straight line, sorry dude

    standard form is not the same as slope intercept form

    and you only need a slope and a point to define a line. 2 points helps to define a slope is all

    standard from is: Ax + By = C

    m = undefined is the slope

    solving the stadard form for y, we get the slope intercept form \[ax+by=c\]\[y=-\frac abx+\frac cb\] given that m = -a/b is undefined would suggest that b=0 Ax + 0y = C Ax = C is the line of an undefined slope

    using the point (3,5) Ax = C A(3) = C , when C/A = 3 in simplest form A would equal 1 giving us: C = 3 therefore the equation of line of an undefined slope at (3,5) is: x = 3
