Question

If x is 0;1;2;3;4 and y is 3;5;7;9;11 what will be the rule
​

Answer 1

+1 would be the rule because everytime the. x goes up the y increases by 1

Answer 2

y = 2x + 3

Explanation:

By looking at the numbers I can see that y = 2x+3

Here is the mathematical way:

find slope between any two sets of numbers

(5-3) / (1-0) = m = slope = 2

so far y = 2x + b b = y value when x = 0

y = 2x + 3
