The equation of line is given as
Step-by-step explanation:
Point on the line given :
We can find the slope of the line first from the given points.
Slope= Undefined.
The slope of the line is undefined which means that the line is parallel to y-axis.
From the points known to us we can tell that the line passes through
∴ The equation of line is given as
