The point on a graph where the x and y values are both zero is called the origin. It is represented by the coordinates (0, 0) and serves as the reference point for the Cartesian coordinate system. All other points on the graph are located in relation to the origin, which helps in determining their position in the two-dimensional space.
point of origin
The domain consists of all values of x for which there is a point on the graph. Similarly, the range applies to all the y values.
Take a few (minimum of two, take 2 only after prior practice) values of x as desired and substitute in the equation to get the y values. Now take a graph and have a scale (usually 1m = 1 unit) and point the x and y values on the graph. Join these points to form a line. This is the required graph
The x values are on the horizontal axis and the y values are on the vertical axis.
The lowest point is y = 0 when x = 0. All other values of y are greater than zero for any other value of x

At the given coordinates where the x and y values intersect
It is a line. There are many ways to graph it using intercepts etc. But, you can pick some x points, plug them in your equation, and find the corresponding y point, The graph those (x,y) values

If the point (x,y) is on the graph of the even function y = f(x) then so is (-x,y)
The lowest point is y = 0 when x = 0. All other values of y are greater than zero for any other value of x
slope means the difference in the y-values over the difference in the x-values. y-intercept means the point at which the graph goes through the y-axis.
I don't understand your question but y=3x is the function of a graph, to graph the function you would plug points into the function such as x=0, x=1, x=-1 and you would find the y values at each point so that you can graph it. In this case the graph is a parabola which has a u shape.
x and y
The curve representing the graph of y against x goes down as you move to the right.
