How would you plot the point #(-4,0)# on the cartesian plane?

Answer 1

Nathan Axel

Two steps are involved in Cartesian Plotting:

For a coordinate #(x,y)#, x is the horizontal movement and y is the vertical movement.

Horizontal Movements: We move left if x is negative and right if x is positive.

Vertical Movements: We move up if y is positive and down if y is negative.

Always start at #(0,0)# where the x and y axis cross. Let's take the point #-4,0)#

We move 4 units to the left because -4 is negative, and we do not move up or down because 0 is neither greater nor less than 0.

As a result, our point is 4 units to the immediate left of the origin.

Plot the point (-4, 0) by moving 4 units to the left along the x-axis from the origin.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
