Answer:
The equation that represents a proportional relationship must have this form:
And the graph of a proportional relationship must be a a line that passes thorugh the origin.
Step-by-step explanation:
Since the graph is not attached, I will give you a general explanation about how to solve the exercise.
The equation of a line that passes through the origin is the following:
Where "m" is the slope of the line.
The proportional relationships have the following form:
Where "k" is the Constant of proportionality.
Therefore, the graph of proportional relationships is a line that passes through the origin.
Therefore the equation that represents a proportional relationship must have this form:
And the graph is a a line that passes thorugh the point
A nonproportional relationship is represented by equations or graphs in which the ratio of the variables does not remain constant, like the equation y = x².
A nonproportional relationship is one in which the ratio between the two variables does not remain constant. In terms of graphs or equations, a nonproportional relationship would not be a straight line when graphed. A simple example is the equation y = x². In this case, as x increases, y increases at a changing rate, not a constant rate, which shows it is nonproportional.
Furthermore, when you graph the equation y = x², it forms a parabola, not a straight line. A straight line would indicate a proportional relationship with a constant ratio, while a curve like a parabola indicates a nonproportional relationship.

please show your work !!
hello students from all over the world ! please , someone be kind enough to help me on this math problem ( if u are in 7th grade or higher u can handle it !) :)
grade of the question : 7th grade
subject : math, please help me thanks !! :)
The arrows indicate that you multiply each one, that way you don't forget in the long run, especially once you get to multistep algebraic equation.
So first you multiply the -7y by the 4 and you get -28y, if you remember a negative times a positive is a negative (I like to think of it as bad things that happen to good people is a bad thing ;) ) Now you take the -7y, because you have to multiply it by both numbers in the parenthesis, and multiply it to the -y, and since when you multiply two y's together it becomes squared it is 7y^2 (squared) and since both are negative, they cancel out and become a positive (bad things that happen to bad people is a good thing in a sense) So therefore your answer for the equivalence is 7y^2 + -28y
Hope that helped, my math teacher has a lot of tricks for remembering this stuff :)
