Use Patterns to Write and Solve Equations

Front

What is a rule in a mathematical table?

Back

A rule describes the relationship between the values of x and y in a table, often expressed as an equation.

Front

How do you express that the value of y is 2 more than the value of x?

Back

The equation is y = x + 2.

Front

What does it mean when we say the value of y is 3 times the value of x?

Back

This means y = 3x.

Front

If y = 4x - 4, what is the value of y when x = 2?

Back

y = 4(2) - 4 = 4.

Front

If y = 2x + 7, what is the value of y when x = 6?

Back

y = 2(6) + 7 = 19.

Front

What is the cost of one Winkydiddle if the total cost for 10 is $35.00?

Back

The cost of one Winkydiddle is $3.50.

Front

How do you write an equation for a table where y is always 2 more than x?

Back

The equation is y = x + 2.

Front

What is the equation for a table where y is equal to x divided by 3?

Back

The equation is y = x/3.

Front

If the equation is y = 2x + 7, what is the value of y when x = 0?

Back

y = 2(0) + 7 = 7.

Front

What does it mean when we say the value of x is equal to the value of y plus 1?

Back

This means x = y + 1.
