A line passes through the points open paren 7 comma 10 close paren and open paren 7 comma 20 close paren Which statement is true about the line?
Answer
A
It has a slope of zero because x sub 2 minus x sub 1 in the formula m is equal to the fraction with numerator y sub 2 minus y sub 1 and denominator x sub 2 minus x sub 1 is zero, and the numerator of a fraction cannot be zero.
B
It has a slope of zero because x sub 2 minus x sub 1 in the formula m is equal to the fraction with numerator y sub 2 minus y sub 1 and denominator x sub 2 minus x sub 1 is zero, and the denominator of a fraction cannot be zero.
C
It has no slope because x sub 2 minus x sub 1 in the formula m is equal to the fraction with numerator y sub 2 minus y sub 1 and denominator x sub 2 minus x sub 1 is zero, and the numerator of a fraction cannot be zero.
D
It has no slope because x sub 2 minus x sub 1 in the formula m is equal to the fraction with numerator y sub 2 minus y sub 1 and denominator x sub 2 minus x sub 1 is zero, and the denominator of a fraction cannot be zero.
