you must substitute x in the equation given :)

examples:

when x is -2

therefore, y = 2(-2) + 3

y = -1

when x is 0

therefore, y = 2(0) + 3

y = 3

when x is 1

therefore, y = 2(1) + 3

y = 5

when x is 3

therefore, y = 2(3) + 3

y = 9

for (b) you only have to plot based on the table ;)

hope this helps

How is a topic different from a theme?
jek_recluse [69]
Hi!

A topic is just a general thing you discuss, with no true moral ending you take away from it. A theme, on the other hand, wants to communicate a life lesson.

Hopefully, this helps! =)
