Answer:
0
Step-by-step explanation:
To find the gradient of any line it is best to use the formula to find it:
[tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
where [tex]y_{2}[/tex] is one of the give value and the other is going to be the other value given.
If you substitute it:
[tex]m=\frac{1-1}{2--2} = \frac{0}{4}[/tex]
which equals to 0 so no gradient
:) Hope it helps
