Question

graph the following lines. 5 a) y = 3 b) x = -2

Explanation:

Step1: Analyze y = 3

The equation y = 3 represents a horizontal line. For any value of x, y is always 3.

Step2: Analyze x = - 2

The equation x = - 2 represents a vertical line. For any value of y, x is always - 2.

Answer:

a) To graph y = 3, draw a horizontal line passing through the point (0,3) on the y - axis. All points on this line have a y - coordinate of 3 and x can take any real - value.
b) To graph x = - 2, draw a vertical line passing through the point (-2,0) on the x - axis. All points on this line have an x - coordinate of - 2 and y can take any real - value.
