What does it mean for a graph to be linear and non-proportional?

Back

A linear graph shows a straight line relationship between two variables, but non-proportional means that the line does not pass through the origin (0,0).

What is the Pythagorean Theorem?

Back

The Pythagorean Theorem states that in a right triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the other two sides (a and b): a² + b² = c².

How can you determine if a linear relationship is proportional?

Back

A linear relationship is proportional if it can be expressed in the form y = kx, where k is a constant and the graph passes through the origin.

If John walks 6 blocks North and 8 blocks West, how do you calculate his distance from the school?

Back

Use the Pythagorean Theorem: distance = √(6² + 8²) = √(36 + 64) = √100 = 10 blocks.

What is a proportional relationship?

Back

How do you find the y-intercept of a linear equation?

Back

To find the y-intercept, set x = 0 in the equation and solve for y.

What does it mean for a graph to be linear and proportional?

Back

A linear graph is proportional if it is a straight line that passes through the origin (0,0), indicating a constant ratio between the two variables.
