If you mean: 2x+4y = 4 then the graph joins the points: (2, 0) and (0, 1)
On the Cartesian plane it is at point of origin whose coordinate is (0, 0)
When x = 0, the point that has (0, y) coordinates will be on the y-axis for any y.
If you mean y = -2x-6 then y intersect the graph at (0, -6)
The origin or (0, 0)

Xmin is the lower limit to the graph that will be displayed. For example, if you graph something and set Xmin to 0, then the bottom of the graph will be where y = 0 (0 being the lowest x value o the graph). (The default for Xmin is -10, where the bottom of the graph is at the line y = -10.)

When x = 0, the point that has (0, y) coordinates will be on the y-axis for any y.
It usually means that the end point is included in the range of values that you are intereted in. For example, a graph of 0 ≤ x < 1 would have a solid dot at 0 and a hollow circle at 1 while a graph of 0 < x ≤ 1 would have a hollow circle at 0 and a solid dot at 1.
If you mean y = -2x-6 then y intersect the graph at (0, -6)
If the discriminant = 0 then the graph touches the x axis at one point If the discriminant > 0 then the graph touches the x axis at two ponits If the discriminant < 0 then the graph does not meet the x axis
sin(0) = 0 but, in general, the sine graph need not start at 0. For example, sin(x + 2) does not start at 0.
The origin or (0, 0)

You may mean, what is the graph of the function y = x^2 + 3. This graph shows a upward parabola with a y-intercept of 3 and a minimum at x=0.
If you mean: 2x-y = 10 then the x intercept is (5, 0) and the y intercept is (0, -10)
