Is y=x+1 proportional relationship?

Understand that a relationship between two variables, x and y, is proportional if it can be expressed in the form yx = k or y = kx. Distinguish proportional relationships from other relationships, including inversely proportional relationships (xy = k or y = kx).

For example: The radius and circumference of a circle are proportional, whereas the length x and the width y of a rectangle with area 12 are inversely proportional, since xy = 12 or equivalently, y = 12x.

Benchmark: 7.2.1.2 Graph of a Proportional Relationship

Understand that the graph of a proportional relationship is a line through the origin whose slope is the unit rate (constant of proportionality). Know how to use graphing technology to examine what happens to a line when the unit rate is changed.

Understand the concept of proportionality in real-world and mathematical situations, and distinguish between proportional and other relationship

On a seperate piece of paper, tell whether y is directly proportional to x. If

so, find the constant of proportionality. Then write a direct proportion

equation.
