What is the slope of the line on which for every point the ordinate is same? DD ffA. fInfinitely large B. fUndefined C. f0 D. fInfinitely small
f
C
Step 1: Let L be the line on which for every point the ordinate is same.
Step 2: So, let P(x_{1}, y) and Q(x_{2}, y) be the two points on line L.
Step 3: Slope of line L = Slope of line joining P,Q = m = ΔyΔx
Step 4: = y  yx2 x1[Use the slope formula.]
Step 5: = 0x2 x1 = 0
