Question

A line passes through the points (7, 10) and (7, 20). Which statement is true about the line?

a.It has a slope of zero because in the formula is zero, and the numerator of a fraction cannot be zero.
b.It has a slope of zero because in the formula is zero, and the denominator of a fraction cannot be zero.
c.It has no slope because in the formula is zero, and the numerator of a fraction cannot be zero.
d.t has no slope becausein the formula is zero, and the denominator of a fraction cannot be zero.

Answer 1

slope = (20 - 10)/(7 - 7) = 10 / 0 (cannot divided by 0)

Answer is d.

d. it has no slope because in the formula is zero, and the denominator of a fraction cannot be zero.
