How do I draw the electric field for this?

Draw the electric field for a positive and negative point charge positioned 5 cm from each
other. Do the same for two negative charges the same distance apart and finally two positive
charges the same distance apart.

i have to make a diagram or chart of a few of these sequences that shows the relationship between the electric fields using rays and pointing towards or from the charge in each of the problems

Here are a few hint questions.
What is the direction of the electric field from a positive and negative charge?
How do you find the value of the electric field a distance from a charge.
Since the fields from the charges have magnitude and direction, try doing a vector addition.
Do this for a few points and you will see the general direction of the field lines.
