A classroom pizza party costs $5 per person, plus an initial fee of $30. If y represents the total cost, and x represents the number of people attending the party, which equation best represents this scenario?

y = 5x + 30

Step-by-step explanation:

The initial cost will never change, so it is a constant in the equation. The number of people attending affects how much will be spent in total, minus the initial fee. Therefore, it is an independent variable that is multiplied by 5, which represents the cost per person.

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

hm let me think hm think think hm think yes
