A fruit stand sells 8-ounce containers of blueberries for $4.00. If y represents the cost of x ounces of blueberries, which equation correctly models this proportional relationship? y = 0.2 x
y = 0.5 x
y = 2 x
y = 4bx

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.

where are the choices?

step-by-step explanation: 4 cause 2+2=4

answer is because 4×10=40

and 98×4= is 392

40,392
