Domain and range of 10x - 2y = 4
Anna71 [15]

Answer:

domain: (-∞,∞)

range: (-∞,∞)

Step-by-step explanation:

You need to convert this into a linear equation (y=mx+b)

So we add 2y and divide by 2 to get y by itself

that gives us 5x-2=y

If you pictures this graph in your head you'll see that the domain and range are all real numbers
