If you are using a calculator just plug it in and hit graph.
If you are doing it by hand, start with making a X-Y Table. Plug in X values into the equation to get a Y value out. Plot about 5 points on the graph to get a basic look at the parabola.
To get the right the values, you want to start with the vertex and go out from there. To start, you need to find the axis of symmetry (-b/2a)
[From the basic equation of ax squared +bx + c] That is the X Value for the vertex. Plug that in to find the Y Value for the vertex.
The more points you find the more accurate the graph but normally 5 is enough (vertex and two on left and right)

Graph mathematical equations?
You can.
You want a graph to solve equations?
No, thank you.
How do i graph two equations when both are in y equals?
You graph each of them separately, on the same coordinate plane.
How do you graph on a ti-84 calculator?
Press Y= to see the equations. Enter and equation in, using x as the variable. (Press X,T,θ,n for an x.) Enter an equation and press GRAPH to see it. (If you need to graph parametric, polar, or sequential equations, press MODE and select the graph type you need. Select FUNC for normal y= equations.)
Is The graph of a system of equations with the same slope will have no solutions?
Yes.
