make a table of values for each equation?

Question

_y=2x+5

Answer 1

Hello Trina,

 

In order for you to make a Function Table, or a Table of values, you need to choose a few values for x.  In this example, I will choose the following values for x: -3,-2,-1,0,1,2,3.  You can choose as many as you want, but try to between 3 and 5 number.  So, what you need to do next is plug in the different values of x into the original equation to find the values of y. Are you ready? Here we go! (sorry about the colors the computer is acting up :( )

 

This is the FUNCTION TABLE

x-value       y= 2x+5                y-value      (x,y)

-3               y= 2(-3) +5        -6+5 = -1     (-3,-1)     

-2               y= 2( -2) +5       -4+5 =  1      (-2,1)               

-1               y= 2 (-1) +5        -2+5=  3      (-1, 3)              

 0               y= 2( 0) +5           0+5=  5      (0,5)                

 1               y= 2(1)+ 5            2+5=  7      (1,7)                

 2               y= 2(2)+5             4+5=  9       (2, 9)

 3                y= 2(3)+5             6+5=  11    (3, 11)

 

I hope this helps and keep asking for help.
