To plot a point on a graph, you need the x and y coordinates.
In this case, the x-coordinate is 2 and the y-coordinate is 2 thus you can plot
(2,2) on a graph.
To get the equation of a line, you need the slope m of the line, a point and another imaginary point (x,y). So in this question you still need the slope to find the equation.
The equation is : No
Answer
1. The point can be plotted on a graph
2. No, the equation can not be determined because the gradient is not known.
