How do you find each y-value for y=2x-5 on a table?

to find a y-value, plug in any number for x in the equation and then solve the equation for y.

if you're given a table that has x-values filled in, plug each of those in for x in order to solve for their corresponding y-value.

if the table is blank, pick whatever numbers you want to use as x-values. don't use any numbers that are astronomically large, though. i always find that the best, most basic numbers to stick with are -2, -1, 0, 1, and 2.

i hope this helps! have a lovely day <3

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y
