Question: How can i plot 3 column Matrix data in 2D plot ?

Good day, I need to 2D plot from points which I get by solving numerically 17-degree equations. Firstly I take an only first solution of the equation as below, and I have a Matrix with 3 column which represents X, Y, and VALUE respectively. On the left side should be the first column ( X ), and right axis Y (2. column). As seen from Matrix X and Y getting the value between 0 and 10. Is there any option that I can plot my data in 2D?  Thanks in advance.

points := seq(seq(seq(Fun[n, i, j], n = 0 .. step), i = 0 .. step), j = 1);
Mat := Matrix((step+1)^2, 3, [points]);
         .                             X                  Y                 VALUE
pointplot3d(Mat, style = point, color = black);
