Answer:
The y's are 1, 3, 5, 7
Explanation:
You have equation y = 2x + 3
You can think of this as a "rule" So whenever you're given a number (a value for x) you put the number in place of the x and times by two then add three.
you were given a list of numbers. They will go one at a time and have a turn being acted on by the rule.
It looks like this: first when x is -1.
take the -1 times by 2 >>>> that's -2 and then add 3 >>>> so you get 1.
y = 2x +3, x= -1
y = 2(-1) + 3
y = 1
You might have a column to write the answers in like next to their x's. Or sometimes we write them in pairs (-1 , 1)
y = 2x + 3; x = 0
y = 2(0) + 3
y = 3
(0, 3)
y = 2x + 3; x = 1
y = 2(1) + 3
y = 5
(1, 5)
y = 2x + 3; x = 2
y = 2(2) + 3
y = 7
(2, 7)
