What is a proportional relationship?

Back

A proportional relationship is a relationship between two quantities where the ratio of one quantity to the other is constant. This constant is known as the constant of proportionality.

Front

How do you find the constant of proportionality from a table?

Back

To find the constant of proportionality, divide one quantity by the corresponding quantity in the other column. If the ratio is the same for all pairs, the relationship is proportional.

What is the equation to find the slope of a line?

Back

Front

What does the slope of a line represent?

Back

The slope of a line represents the rate of change of y with respect to x. It indicates how steep the line is and the direction it goes (positive or negative).

Front

How do you solve a linear equation?

Back

To solve a linear equation, isolate the variable on one side of the equation using inverse operations (addition, subtraction, multiplication, division) until the variable is alone.

Front

What is the solution to the equation 6x + 3x + 20 = 101?

Back

The solution is x = 9.

Front

What is the slope of the line represented by the equation y = rac{3}{2}x + 1?

Back

Front

How do you determine the slope from a graph?

Back

Front

What is the slope of a line that goes down from left to right?

Back

The slope of a line that goes down from left to right is negative.

Front

What is the result of simplifying the expression 5(3x – 4) – 3(2x + 6)?

Back

The result is 9x - 38.
