The electric field at a point in space is the magnitude and direction of the force
that would act on a small test charge if it were located at that point.

Does an electric field have strength but no direction?
It has plenty of direction. The direction of the electric field at any point in it is the direction of the force that would be felt by an infinitesimally small positive charge placed at that point.
Is electric field scalar or vector?
The strength of the electric field is a scalar quantity. But it's the magnitude of thecomplete electric field vector.At any point in space, the electric field vector is the strength of the force, and thedirection in which it points, that would be felt by a tiny positive charge located there.
Electric field is positive or negative?
Did you mean "The strength of electric field is positive or negative"? Anyway, there is your answer.. The strength of an electric field E at any point is defined as the electric force F exerted per unit positive electric charge q at that point, or E = F/q.You can say that it is positive.
How closely packed the electric field lines are indicates the strength of the electric field?
true
How will the electric field strength compare at a 2 m distance point charge?
I don't know. You've neglected to mention what it's to be compared to.

What 3 words that describe weakness?
Weak spot, weak point, Achilles' heel...

Describe an electric field?
The electric field is defined as the force per unit positive charge that would be experienced by a stationary point charge at a given location in the field.
How will the electric field strength compare at a 2 m distance point charge?
I don't know. You've neglected to mention what it's to be compared to.
In which direction does the electric field point at position directly east of a positive charge?
Yes. The electric field in physics is represented by a vector, it has three components governing the field strength in the up-down, left-right and forward-backwards directions.
How can you tell if a point is a solution to the equation?
Substitute the coordinates of the point into the equation and if the result is a true statement then the point is a solution, and if not it isn't.
What is the direction of electric field?
This question is impossible to answer because the force is dependant on the strength of the electric field. This will depend on how many other charges there are and how far away. The strength of an electric field is proportional to the number of charges and the inverse square of the distance. Strength of field = C x N / D2 where C is some constant, N is the number of charges (-ve will repel +ve will attract for and electron) and D is the distance between the electron and the charges creating the field.
How do you determine whether a point is on a given line or not?
Substitute the coordinates of the point into the equation of the line. If the equation is still valid then the point is on the line; if not then it is not.
