How do you determine if a relationship is proportional using a table of values?

Back

If the ratios of the corresponding values are the same, the relationship is proportional.

Front

What is the formula for calculating distance on a coordinate plane?

Back

Distance = √((x2 - x1)² + (y2 - y1)²) where (x1, y1) and (x2, y2) are the coordinates of the two points.

Front

What does it mean to solve for a variable in an equation?

Back

To solve for a variable means to isolate the variable on one side of the equation to find its value.

Front

What is the cube root of a number?

Front

What is the difference between a proportional and a non-proportional relationship?

Back

In a proportional relationship, the ratio remains constant, while in a non-proportional relationship, the ratio changes.

Front

How do you graph a linear equation on a coordinate plane?

Back

Identify two points that satisfy the equation and plot them on the coordinate plane, then draw a line through the points.

Front

What is the meaning of 'solving an equation'?

Back

Solving an equation means finding the value(s) of the variable(s) that make the equation true.
