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 a relationship where y is 2 more than x?

Back

The equation is y = x + 2.

Front

What does it mean when y is equal to 2 times x?

Back

It means that for every unit increase in x, y increases by 2 units, represented by the equation y = 2x.

Front

How do you write the equation for y being x divided by 3?

Back

The equation is y = x/3.

Front

What is the equation for y being 3 times x?

Back

The equation is y = 3x.

Front

How do you complete a table using the equation y = 4x - 4?

Back

Substitute values of x into the equation to find corresponding y values.

Front

What is the output when x = 2 in the equation y = 4x - 4?

Back

When x = 2, y = 4(2) - 4 = 4.

Front

How do you complete a table using the equation y = 2x + 7?

Back

Substitute values of x into the equation to find corresponding y values.

Front

What is the output when x = 3 in the equation y = 2x + 7?

Back

When x = 3, y = 2(3) + 7 = 13.

Front

What is the cost of each Winkydiddle if the total cost is c and the number of Winkydiddles is w?

Back

The price of each Winkydiddle is c/w.
