Write the equation of the line with x-intercept (–8, 0) and undefined slope.?-Collection of common programming errors

• Undefined slope indicates that it is a vertical line with same x coordinate throughout. Slope of the line is (y2-y1)/(x2-x1). since x1 and x2 are same, x2 – x1 =0, since denominator is zero , its slope is undefined so the equation is x = – 8,

  where – 8 is x-intercept

• if a line has an undefined slope, then it is a vertical line. if a vertical line passes through the point (-8,0), then that line must be y = -8

• y = mx +b y = mx y = 0 it is a horizontal line that passes the origin that passes also x = -8 you fool some wise guy . . . . not me

  hehehe
