Can anyone help me? I have this as a discussion question and I am confused.. Throughout this unit, you will participate in a discussion based on the following question: How can you model data with a linear function? Take a moment to consider your response to this question. You must provide a real-world example and show how to model the problem using a linear function. Be sure to explain how you know it is a function.

    consider an example of weight increasing with mass...(physics)... we know that weight = mass* gravity ....so here consider gravity as constant mass= x and weight = y ...you 'll have a linear function as y=k*x

    this is called as linear variation

    one more example is ohm's law...where current (I)is proportional to voltage (V)...(provided that temperature should be constant ) so it is V= I*R where R is constant known as resistance....so V varies linearly with current ..linear variation means equal or proportional increase in one variable for the amount of increase in other

    just consider y= x ...the more you increase x the more y increases...moreover linear means arranged or extending over a line...so values of linear equations will vary in a straight line

    so how would a real life thing fit into this?

    real life thing is a variation of current in a wire....that i have mentioned above...higher the applied voltage (potential difference) higher will be the current ...but if their graph will be plotted it'll be a straight line

    ok soo umm the high you turn up voltage the higher the number but it will be linear on a graph how is that?

    higher the voltage higher will be the current ..but graph between them will be on straight line...since they are linear

    ok im starting to get it i think.. So for my discussion could i use this but put it in my own words? and ill tell you what imma put to make sure its correct.

    Ghazi is this the equation for it? F(x) = m x + c

    yes...it is a linear equation

    so with the votage thing which would be the current and the higher voltage?

    for the voltage thing it would be just voltage= resistance * current or V=I*R

    this work So a real life situation of linear function it a current in a wire. The higher the voltage that is applied the higher the current will be. But if they are plotted on a graph even though they are changing it’ll be a linear line. The equation would look like this voltage= resistance * current.
