Use Patterns to Write and Solve Equations

Write the rule that represents the table.

• The value of y is 2 more than the value of x.

• The value of y is 2 times more than the value of x.

• The value of x is equal to the value of y plus 1.

Write the equation for the table.

• y=2x

• y= x + 2

• x=y - 2

• 2y = 2-x

Write the rule for the table.

• The value of y is x/3.

• The value of y is the value of x times 3.

• The value of y is 3 plus x.

• The value of x is 3y.

Write an equation for the table.

• x= y/3

• 3y = 3x

• y=3x

• x = 3y

Use the equation y = 4x-4 to complete the table.

• 2, 4, 6, 8

• 12, 14, 16, 18

• 4, 12, 16, 20

• 4, 12, 20, 28

Use the equation y=2x+7 to complete the table.

• 9, 13, 18, 22

• 7, 10, 13, 16

• 9, 13, 17, 21

• 2, 6, 8, 10

Which equation describes the pattern?

• y=x+7

• x=y-7

• 4x -1 = y

• y = x+8

The Gadget Factory sells Winkydiddles. The table shows the cost, c, of Winkydiddles, w. If each Winkydiddle costs the same amount, what is the price of each Winkydiddle?

• $4.50

• $42.00

• $24.50

• $3.50

Does the equation z = w -18 make the relationship in the table true?

• Yes

• No

Which equation represents the data in the table?

• t=2d+7

• t = 5d+3

• t=8d -3

• t=4d+5
