construct a graph corresponding to the linear equation
y=2x−6

Since you have a linear equation, in order to draw its graph you just need two points in the cartesian plain. To find this points solve the equation firstly when y=0 and secondly when x=0. After that you have your two points and all you have to do is connect the corresponding dots.
