The slope is ∞ , line is a vertical line parallel to y axis.
What is a Straight Line Function ?
A straight line function is a function that can be represented by y = mx +c , where m is the slope of the line and c is the intercept on the y axis.
There are two points given for a line ,
The slope is represented by
[tex]\rm m = \dfrac{y_2 -y_1}{x_2 -x_1}\\\\m = \dfrac{31-6}{1-1}[/tex]
m = ∞
which means the line is a vertical line parallel to y axis.
