Please I need help no one is trying to help me! How can you identify a linear nonproportional relationship from a table, a graph, and an equation?
From a table, for an ordered pair (0, y), y will not be. From a graph, the y−intercept will not be. From an equation, it will have the form y = mx + b where b is not .

The number 0 goes in all three blanks.

Explanation:

A linear proportional relationship always has a y intercept of 0. Visually, this means the proportional graph will go through the origin. So that in turn means b = 0.

For example, the equation y = 5x is a proportional equation with 5 being the constant of proportion. Whatever x is, multiply by 5 to get y. We can think of y = 5x as y = 5x+0 to see that b = 0 here.

When considering nonproportional equations, we let b equal anything but zero. In other words, b is nonzero in this case. Something like y = 5x+2 is not proportional. The graph doesn't go through the origin and the intercept here is (0,2).

In short, you'll write "0" without quotes into each blank.

believe it or not anna is correct good job anna give me a fist bump there u go gal
