Answer
Slope = ∞
Step-by-step explanation
For a straight line, the slope of the line can be obtained when the coordinates of two points on the line are known. If the coordinates are (x₁, y₁) and (x₂, y₂), the slope is given as
![Slope=m=\frac{Change\text{ in y}}{Change\text{ in x}}=(y_2-y_1)/(x_2-x_1)](https://img.qammunity.org/2023/formulas/mathematics/college/2spudbjlkh14f60l20sveubtri0s31xnrj.png)
For this question,
(x₁, y₁) and (x₂, y₂) are (3, -1) and (3, 4)
![\text{Slope = }(4-(-1))/(3-3)=(4+1)/(0)=(5)/(0)=\infty](https://img.qammunity.org/2023/formulas/mathematics/college/50nrr786bdmh28p3h417o26ubexv7q93sc.png)
Hope this Helps!!!
