Answer:
The equation [tex]y=5x-7[/tex] doesn't represent a proportional relationship.
Step-by-step explanation:
- Proportional equations are those linear equations([tex]y=kx+b[/tex]) where the value of b≠0, i.e. the line passes through origin.
- [tex]y=5x-7[/tex] shows a equation that potrays linear relationship between the variables x and y. This type of equation is an example of non-proportional relationship.
- The remaining three equations are in the form of [tex]y=kx[/tex] where k is the constant of proportionality. This type of equations represent proportional relationship.
