Lesson 1: Coordinate plane (ASL)

# Points on the coordinate plane

Plot points on the coordinate plane in all four quadrants.
In this article, we're going to plot points in the coordinate plane. We'll start in the first quadrant.

### Example: Plotting the point $(\blueD7, \goldD4)$left parenthesis, start color #11accd, 7, end color #11accd, comma, start color #e07d10, 4, end color #e07d10, right parenthesis

Let's start by going to start color #11accd, 7, end color #11accd on the x-axis:
Now we go up start color #e07d10, 4, end color #e07d10, and plot the point left parenthesis, start color #11accd, 7, end color #11accd, comma, start color #e07d10, 4, end color #e07d10, right parenthesis:

### Practice

Problem 1
Plot the point left parenthesis, 2, comma, 8, right parenthesis.

### Example: Plotting the point $(\blueD{-5}, \goldD{-9})$left parenthesis, start color #11accd, minus, 5, end color #11accd, comma, start color #e07d10, minus, 9, end color #e07d10, right parenthesis

Let's start by going to start color #11accd, minus, 5, end color #11accd on the x-axis:
Now we go down start color #e07d10, 9, end color #e07d10, and plot the point left parenthesis, start color #11accd, minus, 5, end color #11accd, comma, start color #e07d10, minus, 9, end color #e07d10, right parenthesis:

### Practice

Problem 2A
• Current
Plot the point left parenthesis, 3, comma, minus, 4, right parenthesis.
