The spanish club held a car wash to raise money. the equation y=5x represents the amount of money y club members made for washing x cars. identify the constant of proportionality. then explain what it represents in this situation.

The constant or proportionality is 5 and it represents the cost of washing per car.

Step-by-step explanation:

Given equation that represents the price of washing of x cars,

y = 5x (1)

∵ by the above equation with increasing x, y increases directly,

⇒ y is directly proportional to x,

That is, y ∝ x (2),

By comparing equation (1) and (2),

5 is the constant or proportionality,

If x = 1, y = 5

Thus, the price of washing per car is 5.

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.
