Answer:
The slop is undefined
i.e. [tex]m=\infty[/tex]
Step-by-step explanation:
Considering the slope formula
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
As the points are (7, -4) and (7, 0)
Here:
[tex]\mathrm{When\:}y_1\ne \:y_2\mathrm{\:and\:}\:x_1=x_2\mathrm{\:the\:slope\:is\:}\infty[/tex]
so
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]=\frac{\left(0-\left(-4\right)\right)}{\left(7-7\right)}[/tex]
[tex]=\frac{0-\left(-4\right)}{0}[/tex]
[tex]=\infty[/tex]
Therefore, the slop is undefined i.e. [tex]m=\infty[/tex]
