Answer:

It has no slope because (x2-x1) in the formula [tex]m=\frac{y2-y1}{x2-x1}[/tex] is equal to zero, and the denominator of a fraction cannot be zero

Step-by-step explanation:

we know that

The formula to calculate the slope between two points is equal to

[tex]m=\frac{y2-y1}{x2-x1}[/tex]

we have

the points (7, 10) and (7, 20)

substitute the values

[tex]m=\frac{20-10}{7-7}[/tex]

[tex]m=\frac{10}{0}[/tex] ----> is undefined

The line has a slope undefined ---> is a vertical line (parallel to the y-axis)
