HOW TO USE THE EQUATION TO COMPLETE THE TABLE.
y=4x+3
x 1 2 5 10 20
y . . . . .
d=3.5t
t 1 2 5 10 20
d . . . . .
This is called a table of values. In the first, put in a x value, and calculate y. For instance, at x=10, y=43
d=3.5t
To use the equation to complete the table, you need to substitute the given values of x or t into the equation and solve for y or d. Let's first complete the table using the equation y = 4x + 3:
For x = 1:
y = 4(1) + 3
y = 4 + 3
y = 7
For x = 2:
y = 4(2) + 3
y = 8 + 3
y = 11
For x = 5:
y = 4(5) + 3
y = 20 + 3
y = 23
For x = 10:
y = 4(10) + 3
y = 40 + 3
y = 43
For x = 20:
y = 4(20) + 3
y = 80 + 3
y = 83
Completing the table using the equation d = 3.5t:
For t = 1:
d = 3.5(1)
d = 3.5
For t = 2:
d = 3.5(2)
d = 7
For t = 5:
d = 3.5(5)
d = 17.5
For t = 10:
d = 3.5(10)
d = 35
For t = 20:
d = 3.5(20)
d = 70
Now you can fill in the table:
For y = 7:
x 1 2 5 10 20
y 7 . . . .
For y = 11:
x 1 2 5 10 20
y 7 11 . . .
For y = 23:
x 1 2 5 10 20
y 7 11 23 . .
For y = 43:
x 1 2 5 10 20
y 7 11 23 43 .
For y = 83:
x 1 2 5 10 20
y 7 11 23 43 83
For d = 3.5:
t 1 2 5 10 20
d 3.5 . . . .
For d = 7:
t 1 2 5 10 20
d 3.5 7 . . .
For d = 17.5:
t 1 2 5 10 20
d 3.5 7 17.5 . .
For d = 35:
t 1 2 5 10 20
d 3.5 7 17.5 35 .
For d = 70:
t 1 2 5 10 20
d 3.5 7 17.5 35 70
