Question

Pls help! I'm confused. Can you explain this if you can.

Answer 1

Answer:

From a table, for an ordered pair (0, y), y will not be zero. From a graph, the y-intercept will not be zero.  From an equation, it will have the form, y = mx + b where b is ≠ 0.

Step-by-step explanation:

• From a table, for an ordered pair (0, y), y will not be zero. If there is not a constant rate of change in the data displayed in a table, then the table represents a nonlinear nonproportional relationship.
• From a graph, the y-intercept will not be zero. This means that it doesn't contain or go through the origin.  
• From an equation, it will have the form, y = mx + b where b is ≠ 0. (not equal to zero). If an equation is not a linear equation, it represents a nonproportional relationship. A linear equation of the form y = mx + b may represent either a proportional (b = 0) or nonproportional (b ≠ 0) relationship.  Therefore, when b ≠ 0, the relationship between x and y is nonproportional.
