Answer:
They Would be if they Have a pattern from left to right such as +2 or -5.
Step-by-step explanation:
If an example is counting up from 15 to 31 and 0 to 8 the pattern is Adding Two. So if the numbers decrease or increase in a certain way, then you can find out what it is and thn bam, your answer to the question.
Why?
Because if you draw a line from A to D to make a triangle AED, then triangle all angle add up equal 180.
(-19,55) x is equal to -19 and y is equal to 55
Because if the number was rational then we can tell by looking at the numbers. The rational number should be one number or a repeating decimal or terminating number. plus because if a number was like this 5.7696... that means its irrational because we dont know the end of the number. The rational numbers are terminating numbers or either decimal or repeating numbers because we know the end of those numbers.
